RFC Lookup - Performance enhancement:

Issue: we are facing an issue that PI is taking more time to process huge amount of messages like more than two thousand for some interfaces, because for each interface there are 40 to 45 downstream systems, so each Idoc has to go through Basis receivers mapping and split messages to select downstream.

Introduction/ Overview

This document is a beginner’s guide for Building & Deploying NWBPM with Human activity steps along with Webdynpro UI. There are no ESR and ID objects created for this scenario.

Prerequisites

• SAP NWDS 7.31
• Administration user on PO 7.31 server to create new users and to deploy a new dc

Procedure

Step1. Create a Development Component

     Click On Next

(6) Click on Next

Click on Finish

The BPM component will be created as shown

Step 2. Create a New Process

(7)Drag and Drop Process from Right Palette into the Business Component

(8) Type “EmpInfo_Process” as name for the new process and then click on “Next”.

     Select “Create a pool with the following names and lanes”

     Enter Pool name as “EmpInfo”

     Enter Lanes “Use1,User2”

     Click on Next

     Leave defaults as it is and click on Finish

(9) Double Click on Employee_Process , following screen will appear

(10) Select the line between Start and End and delete the link/line

      Create the first Human activity for the “User1” Lane as shown below

(11) Type the name of the Human activity “Enter Emp Details”.

(12) Create one more Human activity

(13)  Move the new Human Activity to the Lane “User2” and type “Display Emp Details” as a name for this activity.

(14)  Connect the Human activity “Display Emp Details” with the End event.

      Save (Ctrl+S).

Step 3. Create Web Dynpro UIs by UI template

In this step you create and assign new User Interfaces, based on Web Dynpro Java, for the human activities.

(15)  Remove default task from Human activity “Enter Emp Details”

        Repeat the step for “Display Emp Details”

         Save ALL

(16)  Import the  WSDL by clicking on Service Interface -> Import WSDL

         Check Remote Location/File System and import the WSDL from your desktop and then click on finish

          You can see the following Date types and Service Interface created

(17) Drag and Drop the Data type EmpOnboard_Dt from Project Explorer to Swim Lane User2

(18)Select process in Project Explorer and right mouse click

     Select Apply Template

(19) Select UI Task Generation

      Click Next

(20) Fill Display Emp Details and check the checkboxes

(21) Fill Enter Emp Details and check the checkboxes

      Click Next

(22) Click Finish and Wait for the wizard to generate the UIs

(23) After the successful generation the NWDS will look as follows

Step 4. Create Users and Grant Access

In this step you wo;; create new users . Later on you will assign these users to the swimlanes in BPM. These users will participate in the process and will receive the tasks.

(24)  Open SAP NetWeaver Application Server Administration > User Management

         ex: http://<ip>:<port>/startPage

(25) Create User

(26) For the First UserID type “User1” for Logon ID, type password 123pass, confirm it and type “User1” for the Last Name of this UserID (see the example).               Click “Save” at the end.

      Complete the same for the UserID type “User2”.

(27) Following Users will be created

(28)  Assign Users to Roles. Change the Search Criteria to Role

(29) Search for a Role containing “BPEM” – type for the search criteria *BPEM*. Click on “Go”.

      Click on the displayed Portal Role with description “BPEM End User”.

(30) Go to tab “Assigned Users” and click button “Modify”.

(31) Search for the “User*” and click on “Go”.

(32)When found, select all rows .Add UserIDs to the role

(33) After the assignment both UserIDs will be displayed on the right side with Assigned Users. Click on Save

(34) Search also for the Portal Role “Every User Core Role”. Click on the role.

(35)Go to tab “Assigned Users” and click button “Modify”. And repeat steps (31),(32) and (33)

Step 5.Assign Users to Swim-Lanes

(36) Click on Swim Lane User1 and  and select “Potential Users” in Properties tab

        Click on Choose...

     Search for “User1" , Select User1 added in the last step , Click OK

     Similarly, Select the Task swimlanes User2 and select “Potential Users” in Properties tab

     Click on Choose...

     Select User2 added in the last step

     SAVE ALL

Step 5. Create Mappings

(37) Select the Task “Enter Emp Details”> Go to Properties > Output Mapping >Map the fields as shown

(38) Select the Task “Display Emp Details”> Go to Properties > Input Mapping > Map the fields as shown . Save (Ctrl+S).

Step 6.Build & Deploy the process

(39) In Process Composer perspective: Build the DC

(40) Select also the development component of the Web Dynpro Development Component if you want to re-build it and click “OK”.

(41) In Process Composer perspective: Deploy the DC

(42) Deployment starts.Log shows the BPM is deployed successfully

Step 7 .Run the process

(43) Click on SAP Netweaver Administrator . Search for Process Repository -> Go

       Click on Overview

       Select the Process “bpm_empinfo_humanactivity ~pr~pm(example.org)” from the list with Components.

(44) Go to Resources of the Component > Processes and Tasks - select the Process Definition “EmpInfo_Process”. Click Start Process.

(45) A new pop up appears Click Start Process

(46) A message for successful process start will appear at the top of the screen.

Step 8 .Test the Process Behavior with “User1” and “User2”

(47)  Log-in to the Portal -> http://<ip>:<port>/irj using User1 and the initial password 123pass.Change the initial password to pass123

(48)A task is already assigned to User1 and is visible in the Task list of his Universal Worklist.

      Click on the Task/ Open the task

(49) A new pop up appears .Go to the link of the Process to see where you are on the process flow.

(50) You are on the first Human activity “Enter Emp Details”.

(51) Enter the Details and click on Approve button

(52) Refresh the Universal Worklist , task will disappear

(53) Log-in to the Portal using User2 and the initial password 123pass. Change the initial password to pass123

(54) The next process task is already assigned to User2 and is visible in the Task list of his Universal Worklist.

(55)Go to the link of the Process to see where you are on the process flow. You are on the second Human activity “Display Name Age”

(56) BPM UI is now displaying the Emp details values entered by User1 earlier. Click on Approve button

(57) Refresh the list with Tasks in the Universal Worklist of User2 . Task will disappear

This completes our hands-on scenario

Objective: To calculate MD5 checksum value of a flat file and send this value in a checksum file to FTP/SFTP server.

Approaches Tried:

We use following approaches in general to achieve certain functionality which is not readily achieved in SAP PI.

• Modules from SAP.
• Java mapping through customized .jar files.
• OS command lines.
• User Defined Functions (UDFs).

Details on various approaches:

• Modules from SAP:

We do not have any inbuilt module in SAP PI which can generate checksum of a file especially a non-xml file. Writing a customized module requires larger efforts and expertise to develop and deploy.

• Java mapping through customized .jar files:
  • This is most popular approach of attaining some functionality which is not readily available with in SAP PI.
  • Java mapping uses .jar files which are used in Integration Engine with in SAP PI.
  • It operates on XML form of data and suitable for the nominal file size which PI can process without altering its performance.
  • With respect to our requirement it has two shortcomings:

1. It receives data from source side in the form of xml into an input stream. It performs operation on this xml and xml tags. But we need to calculate checksum on a flat file not on its xml version.
2. It uses ESR objects to identify source data. As it is a quarterly activity and files will come in chunks of 5 MB – 10 MB, the final file will have a size of >= 40 MB. It is huge file and will get stuck in PI and will not get processed.
3. We need to calculate checksum on whole file; not on its individual chunks.

• Owing to above shortcomings we cannot employ this approach to generate MD5 checksum.

• OS command lines:
  • We do not have any inbuilt command line to generate checksum for SAP PI on windows server.
  • OS command can be used with MD5 checksum utilities available on internet but that may expose system to malware.
  • Using a java program through OS command line efforts at par with developing a UDF or java mapping which are easier to implement.
  • Most importantly it is difficult to track any failure in OS command line as the communication channel never displays any error if OS command line does not run properly.

• User Defined Functions:
  • UDFs are easier to develop, compile and deploy.
  • Though UDFs too use ESR objects but it may operate independent of the data being processed.
  • UDFs have advantage that PI server (AL11 Path) is directly accessible to it.
  • UDFs can be written to operate on a flat file (in AL11 path) of any size without converting it to XML.

• Why do we choose UDF over other approaches?

• UDFs have advantage that it can operate on flat files as a whole though it operates in integration Engine.
• The flat files (for which we need to calculate checksum) on PI server (AL11 path) are always at its disposal.
• The interface using this UDF can be run whole day, thus constantly searching for the files on the path for which checksum is needed to be calculated.
• It performs MD5 Checksum logic on flat file not on its xml version.
• It does not use ESR objects of the file for which checksum is needed to be calculated thus not converting the file to xml  adding to that whatever be the size of the file it can calculate checksum value without putting any load on PI once the file is available on AL11 path.
• We can use same UDF to calculate checksum of any number of interfaces with any file size.

• Conclusion:
  • UDFs can operate on flat file without changing it XML
  • UDFs can operate on flat file of any size thus be ridding PI of any stress due to file size.

• Process of implementation:

• We are implementing the UDF in message mapping itself as shown below:

• The Complete Code is:

------------------------------------------------------------------------------------------------------------------------------------------------------------------

try

{

  String Path = "<File path on AL11>"+"Filename";

  String datafile = Path;

         MessageDigest md = MessageDigest.getInstance("MD5");

         FileInputStream fis = new FileInputStream(datafile);

         byte[] dataBytes = new byte[1024];

         int nread = 0;

         while ((nread = fis.read(dataBytes)) != -1) {

           md.update(dataBytes, 0, nread);

         };

         byte[] mdbytes = md.digest();

         //convert the byte to hex format

         StringBuffer sb = new StringBuffer("");

         for (int j = 0; j < mdbytes.length; j++) {

                    sb.append(Integer.toString((mdbytes[j] & 0xff) + 0x100, 16).substring(1));

         }

         return sb.toString();

}

catch (Exception e)

{

return "Error";

}

---------------------------------------------------------------------------------------------------------------------------------------------------------

You will be needed to place the file in any AL11 path which is accessible to SAP PI service User.

• This UDF can be used in message mapping:

• Which in turn generated MD5 checksum of the file abc.csv (test file) which is place on some AL11 path as shown below, accessible to UDF and will pass the MD5 checksum value to target field which can be redirected to generate a checksum file on FTP/SFTP server.

• The final checksum file will look like as shown below. (The text with in file can be customized in UDF)

* Please note that the above process is very Basic approach to calculate MD5 checksum. It can be implemented directly on FTP server instead of first moving file to AL11 path. For which you will need to use the library org.apache.commons to use FTP upload download. You will need to get this library placed on PI server to be able to import it while developing UDF.

How to get an XML file from Web page using JAVA Mapping

Context:

The main aim of this document is to explain how to transfer IDoc data from one system to another for testing purposes.

Scenario:

We need to perform end to end test for an outbound IDoc scenario in the development environment using the IDoc data present in ECC production system.

Procedure:

• Create a test directory in production ECC FTP server. Ex: /sapinst/IDOCflatfiles

• Note the production IDoc number.

• Execute the T-Code WE19 and enter the IDoc Number and press F8.

• Click on inbound file.

• Enter the directory along with the filename (/sapinst/IDOCflatfiles/FileName) which you created earlier in production FTP. Make sure that Start IDoc inbound processing of file immediately is unchecked and hit enter or execute.

• Now you can find a file created in the directory that was created.

• Transfer this file to your desktop.

• Create a test directory in the development ECC FTP server. Ex: /sapinst/IDOCflatfiles_Target

• Transfer the file from your desktop to the directory that was just created in the development ECC FTP server.

• Login to the development ECC and execute WE19 T-Code. Select File as template radio button. Enter the directory along with the file name and execute.

• Now the IDoc data is transferred from production system to development system for testing. Control record values have to be verified before testing.

Last week I was given a synchronous wsdl and asked to develop a sync-sync interface (SOAP-Proxy). I imported it in ESR, developed the interface and was all set to test.

I opened SOAP UI, imported the wsdl and started mock service. Triggered proxy message from ECC.

And boom –

HTTP 500 Internal Server Error

Then I revisited all the configurations, felt everything is fine. Retested the scenario. And again - 500 exception

I tried to get the logs from SOAP UI. Found the below error:

ERROR: An error occured [Missing operation for soapAction [] and body element……

I’ve set Require SOAP Action property to ‘False’ in SOAP UI and tested. – Same issue again.

I was wondering where could be error. When I investigated the wsdl I found that SOAP binding was Remote Procedure Call (RPC) style. Generally, we use document style binding.

In external definitions in ESR when we import a wsdl, by default Messages option will be set to “From All Available Message Definitions”

But, when we import wsdl with RPC style binding, we have to change it to “Using RPC Style”.

Finally, when I made these changes, my scenario was successful.

Problem Faced:

Unable to add SAP AS Java in NWDS.

I had a scenario wherein I have to deploy a custom adapter module. Traditional way of doing it is by registering the SAP instance and then deploying the EAR file on the desired server.

But, when I tried to register the SAP instance by giving Instance host name and instance number and clicking OK, nothing happened. When I entered a wrong host instance name or a wrong instance number the NWDS showed me an error message. Otherwise, if everything is correct, it just closes the popup window and returns to the SAP AS Java initial screen with no system on it.

When I tried deploying the module without registering the SAP Instance, NWDS showed NullPointerException.

Resolution:

1. Stop the server

2. Open DEAFULT.PLF file in “/usr/sap/(SID)/SYS/profile”

3. Set the parameter “service/protectedwebmethods” to DEFAULT

4. Restart the server

In most of the projects, BASIS team will have the access to above mentioned directory. Asking BASIS team to perform the above activity is recommended.

Hello All,

Here I want to share a small helpful document, which I have experienced in my POC. We all know the concept of EOIO in SAP PI. Now we are going to consider the same, suppose if we are processing an EOIO message using BPM with multiple conditions and similarly routing the messages to multiple systems based upon conditions.

Problem: Consider 5 messages which have to go to 3 different systems (A, B, C) based on conditions.For example message 1, 2 to System A, message 3 to System B and Message 4, 5 to system C. If any kind of error occurred for any of the messages 1 or 2 then rest all of the messages will be on scheduling state along with the messages of systems (B, C).

Solution: Instead if we have three different queues for each system then that particular message of that system will be on hold instead queuing up of all the messages of other systems and it is also easier to check and monitor the queues. Here we go with an example for the same.

In every BPM we will have the below following steps according to the requirement.

Transformation: Here, as we discussed earlier we need to route the messages according to the conditions all the transformation starts for the mapping and final messages will be routed to three different systems.

ForkStep: Here we have final message routing to three different systems.

Send Step: I am going to maintain the queues (A, B, C) in Send step of a BPM. As we have three different systems namely A, B, C in our example we will take the same now. After the fork step we will have a send step where we are going to have our queue maintenance.

In each of the send step I have specified different Queue names (A, B, C) .Below is the screen shot where I have mentioned the queue name with three different system names.

Now we will monitor the messages in SXI_MONITOR with the different queue names

In the above screen shot you can observe messages flowing through three different queues. Similarly if any issue comes to any of the queue that particular queue effects instead of other systems. Please reach to me if you have any kind of queries regarding the same.

Dear All,

Here I have tried a small POC to handle CDATA input and create a target payload using Java Mapping.

Input structure:

Target Structure:

Input payload:

<?xml version="1.0" encoding="UTF-8"?>

<ns0:Source_DT1 xmlns:ns0="urn:NGM:POC">

   <Root>

      <Field1><![CDATA[<?xml version="1.0" encoding="UTF-8"?> <ns0:Source_DT1 xmlns:ns0="urn:NGM:POC"> <Root>       <A>A</A>       <B>B</B>                 <C>B</C>    </Root> </ns0:Source_DT1>]]></Field1>

   </Root>

</ns0:Source_DT1>

Mapping Explanation:

In input value Field1, We are getting XML contains values for A, B and C. So we have to get the values for Target Fields A, B and C from input Field1 XML value and create target.

Java Mapping:

This is handled through Below Java mapping:

We are creating target structure from the field1 CDATA value.

Here is the java mapping which I had used to create target payload:

public void transform(TransformationInput arg0, TransformationOutput arg1) throws StreamTransformationException {

String inputPayload = convertInputStreamToString(arg0.getInputPayload().getInputStream()); // Calls convertInputStreamToString function

String output = "";

String outputPayload = "";

output=inputPayload.replaceAll("<.*?>", "");//Regx to remove everything between "<>" characters

output=output.replaceAll("]]>", "");//replace the charcters with empty

output=output.replaceAll("\\s+", " ");//Regx to remove the extra spaces

try {

StringTokenizer st = new StringTokenizer(output, " " );

        String[] strFileArray = new String[4];

        int i = 0;

        while (st.hasMoreTokens()) {

strFileArray[i] = st.nextToken();

            i++;

        }

//-------------Creating target structure------------//

outputPayload = outputPayload .concat("<?xml version=\"1.0\" encoding=\"UTF-8\"?>").concat("\r\n");

outputPayload = outputPayload .concat("<Target_DT1>").concat("\r\n");

outputPayload = outputPayload .concat("<Root>").concat("\r\n");

outputPayload = outputPayload .concat("<A>").concat(strFileArray[0]).concat("</A>").concat("\r\n");

outputPayload = outputPayload .concat("<B>").concat(strFileArray[1]).concat("</B>").concat("\r\n");

outputPayload = outputPayload .concat("<C>").concat(strFileArray[2]).concat("</C>").concat("\r\n");

outputPayload = outputPayload .concat("</Root>").concat("\r\n");

outputPayload = outputPayload .concat("</Target_DT1>").concat("\r\n");

/*

* Output payload is returned using the TransformationOutput class             

* arg1.getOutputPayload().getOutputStream(

*/

arg1.getOutputPayload().getOutputStream().write(outputPayload.getBytes("UTF-8"));

} catch (Exception exception1) {

getTrace().addWarning("Exception caught in Transform: " + exception1.toString());

}

}

/* <<< Reads input payload>>>*/

public String convertInputStreamToString(InputStream in) {

StringBuffer sb = new StringBuffer();

try {

InputStreamReader isr = new InputStreamReader(in);

Reader reader = new BufferedReader(isr);

int ch;

while ((ch = in.read()) > -1) {

1. sb.append((char) ch);

}

1. reader.close();

} catch (Exception exception) {

getTrace().addWarning("Exception caught in convertInputStreamToString: "+ exception.toString());

}

return sb.toString();

}

Final Output:

Fianl target payload and sturucture will looks as below.

Target Payload:

            Hi folks! Working with Adapter-modules has always been challenging and great to use for typical business requirements dealing with Excel files. Excel files carry most of the financial data in current business landscapes. Being one among those who faced such challenge, here I would like to share one of my recent works on Adapter module that deals with Excel files.

This blog explains the way an adapter module can be designed in a simple way and this is unique in the manner that it is generic in nature converting .xls and .xlsx files into XML for SAP PI to process.

  Here we go!  All you need to do is, just follow the below steps.

1.     Create the Data Type for the excel sheet that you want to read.

2.    Techie Buds, please follow the below link to know basics of creating an Adapter module in SAP PI. 

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa?overridelayout=true

3.          Add the below Jars to your module

           poi-3.9.jar

          poi-ooxml-3.9.jar

          xmlbeans-2.3.0.jar

4.    Add the below attached java code in your project

5.     Configure the Sender channel parameters as per your data structure.

UDF : In my business scenario I created the below  UDF ,which maps the first occurrence of the field in XML (Cell Data) to Field 1 (Project Id) on the target side ,2^nd occurrence(Cell Data[2]) to Field 2 (Project Engineer). This way all the data in the XML file will be mapped to the actual fields on the target side for further processing. Isn’t it a simple one?

Testing:

Let’s test a file of .xls and .xlsx by placing in the FTP server for PI to pick.

Output XML file equivalent to EXCEL file read by the module , made available in Target FTP.

XML File :

  How did this approach help me?

• By using this module I converted my Actual Excel file to an intermediate XML file.
• The XML file is just like any other XML that we use in File based scenarios.
• Excel file based scenario is now turned to XML file based scenario using this scenario.
• The Adapter module has become a reusable one, as most of the financial data will have similar format the same can be used.

Document Objective:  Objective of this document is to providing information about “How to Build SFSF OData query “filter Clause” dynamically at runtime using SAP PI synchronously?”

Normally SFSF OData Sender and Receiver Communication channel supports a hard coded Query.

1. e.g.

Operation Type: Query

Operation Query:  dummy-tableName?$select=dummy-fieldNames &$filter=dummy-filterCondition.

Now as you see in above query filter expression and condition is also included as part of actual written query in Communication Channel (hard-coded).

But our requirement is to build and add this filter expression and condition at runtime rather than doing as fixed/hardcoding.

This document provides an example of main steps required to build interface in SAP PI. This is further divided into following three steps:-

1. 1. PI Enterprise Service Repository Configurations
2. 2. PI Integration Directory Configurations
3. 3. Unit Testing of Scenario.

Brief about Technical Scenario:

SAP HCM is sending Employee Numbers to SAP-PI. Based on this request message a dynamic where/filter clause will be formed in Message mapping then it will be appending with actual Query on runtime and will be sent to Successfactors.

Synchronous scenario flow would be as follows:-

1. 1. Response Message will flow from SAP HCM to Successfactors
2. 2. Response Message will flow from Successfactors to SAP HCM.

SAP HCM is SOAP – XI Proxy Sender Channel.

Successfactors is SFSF Receiver Channel.

Enterprise Service Repository:-

External Definition :

Request Message will  from SAP HCM to Successfactors

External Definition (This is delivered by SAP in their latest patch). I have attached external definition along with this document.

I have attached it in txt format. so before using it save it in xsd format and use it.

Note (Just for others information)

You can also create your own data type name, message type but name and its namespace should be fixed as defined by SAP.

Response Message flow from Successfactors to SAP HCM.

External Definition (This is generated from eclipse Juno - How to generate this xsd using Juno: Please follow my other blog).

URL to Blog:

Service Interface

Outbound Service Interface:

Inbound Service Interface:

Message Mapping and Operation Mapping

My is pass-through Scenario so no message and operation mapping required.

Integration Directory:-

1. Sender Communication channel.

2. Receiver Communication Channel.

Focus on Target Channel Arrow and Double Click.

Channel Properties will be Open.

Choose AdapterType as Successfactors

Message Protocol as SOAP ( Note : For OData choose OData Message Protocol).

Fill the neccessry information.

Eg. Address of SFSF DataCenter . In our case it is API5.

Company ID– User– Password( Ask above information from SFSF Configuration Expert ).

3. I-flow

Important Note:

SAP recently released patch to support pulling complete data from Successfactors with an upper limit of 25MB.

It will be good for customers if they can download latest PICOASUF and PIADAPTERS.sca from the SMP and apply both to the PI system.

Starting from SAP Process Orchestration, the new ONE Integration Solution came out. SAP Process Orchestration not only a composite system combine PI,BPM and BRM together, but also makes system technical integration transform into business integration from high level integration view. However it is not easy to understand this superior integration concept of SAP PO until you really implemented some complex integration scenario. In this article, I will present two scenario implementation with detail procedures as practice to let PI consultant adapt to PO consultant model and get the idea about how SAP PI integrate with SAP BPM in SAP PO from technical view.

https://scn.sap.com/docs/DOC-58723

Hello All,

Business Requirement: We had to route the file to different folder using company-code as routing condition available in the file name. Since there was no transformation required so it was basically a pass-through scenario. But since we had to fix the receiver directory during runtime we decided to use java mapping to set dynamic configuration Filename and Directory parameters. We have SFTP as sender and Reciver channels and we were using ICO for configuration.

Its basically a pass-through scenario with choosing the directory/Filename during Runtime.

So it gives an insight of three aspects:

1. How to configure Pass-through scenario and still use Java Mapping.
2. How  to put things together with ICO with SFTP adapter.
3. How to work on java mapping using Eclipse Editor with new API's.

ESR Objects:

• We need to create below mentioned objects
  • Sender Data Type (Dummy structure)
  • Sender Message Type
  • Sender Service Interface
  • Receiver Data Type(Dummy structure)
  • Receiver Message Type
  • Receiver Service Interface
• Imported Archive

• PFA Java Mapping Sample Code which can be edited as per requirement.(Step by Step explained in below section)

• Operation Mapping.

Note: We need not worry about sender structure not matching the input File.

ID-ICO Configuration.

• ICO Inbound Processing:

Note: We have to leave the SWCV of sender Interface blank otherwise we might get an error as Adapter engine expects the the file in sender Data Type.

• ICO Receiver:

• ICO Receiver Interfaces:

• ICO OutBound Processing

• ICO Sender Channel with Advanced module Parameter
  

Note: We don't need to add anything in Module parameter for content conversion.Just need to leave with default entry.

• ICO Receiver Channel with Advanced module Parameter

Note: We don't need to add anything in Module parameter for content conversion.Just need to leave with default entry.

Java Mapping Using Eclipse Editor.

• Step 1

• Step 2

• Step 3: Right Click on Project-> Properties -> Java Build Path -> Add External Jars.

• Step 4

• Step 5

• Step 6: Now paste the code provide and edit as per your requirement.

• Step 7: Right Click on Package you are working --> Export

• Step 8:

• Step 9:

• Just Press on Finish and import it through Imported Archive as mentioned above.

I  know this might not be a difficult one but now this gives us lot of flexibility with other scenarios.

• PGP Encryption:Supposedly if we want encryption we can add pgp module parameters and do encryption in the receiver channel.
• Complex Dynamic Filename configuration.

Hope this solves few problems.

Please share if it requires any changes.

thanks and regards

Praveen Tirumareddy.

2012 Global SAP NetWeaver PI Survey

What is Global Variable?

The variable which is accessible to whole program i.e. having global scope throughout a program is called as Global Variable. Here in PI we are actually referencing a definition w.r.t to JAVA as the base of our SAP PI graphical mapping is JAVA only.

What is the need of Global Variables in SAP PI mapping?

There are the cases where we need to pass\share some information or values in PI mapping among all the UDFs. Suppose for e.g. we have multiple UDFs in one graphical mapping which executes in one sequence. One UDF sets some parameters or variables based on any conditions that will be used by another UDF for sending alerts or for some internal validation in PI. These kinds of requirements can be solved by using Global Variables whose scope will be throughout the mapping or all mappings (the Information of deciding scope will be shared below)

How to define GLOBAL VARIABLE in Sap PI Mapping?

There are two ways to define a global variable in SAP PI Mapping.

Method 1: In the Mapping itself (as shown in below screenshot)

We have one ICON in the Message Mapping (Edit Java Sections) which allows us to declare Global Variables which are having scope to the same message mapping in which it is defined. All the UDFs which are created in that mapping can use those variables.

Now when you click on the ICON you will be getting a window where you can declare global variables and can initialize with a default value (as shown below)

Three variables are defined and are initialized as you see in the screenshot. Now these variuables can be used in UDFs.

Set it in one UDF like and use it in aother as 

Method 2:

In second options we will be creating a JAVA Mapping which will be imported in SWCV as Imported Archives and this allows us to use a Global Variable throughout all the mappings defined in the SWCV. So in this case the scope of our variable is increased to mappings not limited to UDFs.

The only thing we need to take care of that we need to initialize the global variables everytime when you are using it in UDF otherwise it will read the old values set by any other mapping or UDF. Also you need to import class name in import section of UDF and use variable as <ClassName>.<VariableName>

The Code is:

In Imported Achieves it will be like:

In Import Section of UDF, import your class like

In UDF set variable like this:

and use it like this 

Document Objective: Objective of this document is to providing information about that “SFSF SOAP Channel supports for UDF based Lookups”.

This document provides an example on implementation of SFSF lookup UDF in PI Enterprise Service Repository.

Brief about Technical Scenario:

For each person_id_external Lookup Query will bring back the id from SFSF User Entity.

E.g. Input <external-Id > 346 and Output < id > would be USR-22.

Step I. Include following packages.

Step II. add UDF with following paramters.

Step III. UDF Code.

AbstractTrace trace = container.getTrace();

String Var_Username ="";

for (int inlen = 0; inlen < Var_ExternalID.length; inlen++)

{

Var_Username = Var_Username+","+"'"+Var_ExternalID[inlen]+"'";

}

Var_Username = Var_Username.substring(1,Var_Username.length());

try

  {

Payload SOAPOutPayload = null;

String SysName ="";

String BuisnessSysName ="";

BuisnessSysName = "SUCCESS_FACTORS_DEV";

Channel channel = LookupService.getChannel( BuisnessSysName,"Common_SF_SFAPI_Receiver");

SystemAccessor accessor = LookupService.getSystemAccessor(channel);

String SOAPxml ="<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:query
xmlns:ns0=\"urn:sfobject.sfapi.successfactors.com\"><ns0:queryString>Select id,externalId from User where externalId in ( "+Var_Username+")</ns0:queryString></ns0:query>";

InputStream inputStream =new ByteArrayInputStream(SOAPxml.getBytes());

XmlPayload payload = LookupService.getXmlPayload(inputStream);

SOAPOutPayload = accessor.call(payload);

InputStream inp = SOAPOutPayload.getContent();

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.parse(inp);

document.getDocumentElement().normalize();

NodeList list = document.getElementsByTagName("id");

NodeList Elist = document.getElementsByTagName("externalId");

for (int temp =0; temp < list.getLength(); temp++)

{

Node node = list.item(temp);

Node Enode = Elist.item(temp);

if (node != null)

{

node = node.getFirstChild();

Enode = Enode.getFirstChild();

if (node != null)

{

result.addValue(node.getNodeValue()+"||"+Enode.getNodeValue());

}

}

}

}

catch (Exception e)

{

trace.addWarning("Error" + e);

  result.addValue(e);

}

Step IV: Communication Channel.

Step V : Testing and UDF Execution

Step III. Configuration of Eclipse Juno : - Modelling:

1. Auto XSD Generation for Mapping - The SFQL when modeled using the operations modeler generates an XSD file which can be used mapping purposes.

2. Auto Query/Resource Path genaretion for Communication Channel. - It generated SFQL which can be further used in SFSF Communication Channel.

Creating a New Integration Flow and Project. Choose Integration Flow. Commonly known as "IFlows".

Dummy IFlow will be created.

Focus on Target Channel Arrow and Double Click.

Channel Properties will be Open.

Choose AdapterType as Successfactors
