Parameterized Transformation in BPM- Null Pointer exception

[justin_santhanam]

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!

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

Yes sir. I did tested both Message Mapping and Operation Mapping in ESR.

I guess I'm missing one very important step.

in Message Mapping - Signature tab we are defining Import parameter(Adapter type) for lookup - Fine

in Operation Mapping - Parameters tab we are defining Import parameter(Adapter type) for lookup and binding it- Fine

in BPM Transfomation- Configurable Parameters we are defining Import parameter(Adapter type) for lookup and binding it- Fine

While doing testing in Message Mapping and Operation Mapping we are defining the communication channel in the Test parameter tab, But during runtime how it will know which channel to choose ? - If I get answer for this I guess my questions will be solved.

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
