Implementation of Bridge without using BPM (Using JAVA mapping)

By Sabyasachi Masanta

1.0 Introduction  

It is often found that the scenario like bridge is usually implemented with BPM technique in exchanged infrastructure (XI). But BPM has some performance issue. For that reason many clients want to by pass the BPM.

This document enables the developer to implement a scenario of bridge without using BPM. This scenario is developed with the help of java mapping.  

2.0 Business Requirements

We need to create the following bridge scenario.  

Here we need to send a file (contain company code) to the SAP XI. In XI we have used java mapping. This java mapping is calling the RFM (BAPI_COMPANYCODE_GETDETAIL) from ECC. We are sending company code and getting company name and city from ECC. And this company name and city are sending to the output file server.  

3.0 Methodology  

STEP 1 Create the outbound and inbound data type. For outbound data type we are using COMPANYCODEID and for the inbound data type we are using COMP_NAME and CITY.  

STEP 2 Create outbound (using data type “Outbound_DT”) and inbound (using data type “Inbound_DT”) message type.  

STEP 3 Create outbound (using message type “Outbound_MT”) and inbound (using message type “Inbound_MT”) service interface.  

STEP 4 Create the java mapping. First of all get the company code from the “COMPANYCODEID” tag.

NodeList n1 = document.getElementsByTagName("COMPANYCODEID");

Now call the BAPI (BAPI_COMPANYCODE_GETDETAIL) for the company code.

IFunctionTemplate funcTemp =                         mRepository.getFunctionTemplate("BAPI_COMPANYCODE_GETDETAIL");  

Get the company name and city in a variable.

result = returnStructure.getString("COMP_NAME") + "," + returnStructure.getString("CITY");  

Create the company name node and city node with their respective values.

buf_writer.write("<COMP_NAME>" + st.nextToken() + "</COMP_NAME>");

buf_writer.write("<CITY>" + st.nextToken() + "</CITY>");

Export the java mapping into a .jar file. Now create imported archives and import the .jar file.  

STEP 4 Create Operation Mapping and use the above imported archives (java mapping).  

Now go to the “Test” tab and test the Operation Mapping with the valid company code.
