Parameterized Transformation in BPM- Null Pointer exception

Dear All,

I'm doing RFC Lookup in the mapping Transform inside BPM. I have defined the parameters in Message Mapping, Operation Mapping as well as Configurable parameters in Transformation step inside BPM. I don't know if there are any additional steps needs to be done.

If you have any thought on the below error, can you please help me out?

Thanks!

    • Ok Friends,

      I got the solution. In the Integration Directory, you need to double click on the Integration Process and on the Parameter tab choose the communication channel.

      After doing this, my mapping program went through fine.

      Need to get used to lot of new stuffs 😊

    Hi,

    Have you confirmed that your mapping is working fine along with RFC lookup. (Test tab in ESR)

    Also try using Interface mapping instead of message mapping in transformation step and make sure that you have provided the input parameters for RFC in BPM.

    Thanks
