Calrification on Grpahical mapping at Run time in PI7.1

[Former Member]

Hi All,

As I understand,the pipeline service is executed in Integration Engine which is on ABAP stack.The graphical mapping is executed on the Java stack as a class.So how does the mapping pipeline service invoke the java stack?Its bit confusing for me as in architecture diagrams ,BPE and IE are shown as ABAP and AE is shown as Java.And if pipilne service is running on IE,the mapping invocation is not clear to me.Should the IE diagram block also need to show the java stack to make things clearer?

Hi,

Mapping programs get executed on JAVA stack only

pipeline step Call Mapping will make a call to java stack using RFC Communication AI_RUNTIME_JCOSERVER.

where the mapping gets executed and the response is sent back and the rest of the pipeline steps get executed..

Thank you all for your responses.

there happens a JCO call between the ABAP and JAVA stacks during runtime....during this call the details are pulled.

I remember seeing this in one of the TBIT materials (dont remember the number now)....may be the one which shows basics of SAP XI.

Abhishek.
