How to see which function module is responsible for filling the outbound idoc during BCM?

[sharonphilip]

Hello...
There is an issue with the outbound idoc that is created from the BCM process(Bank communication management)...
The segments are being filled with some incorrect values after the BCM approval and I want to debug and see how these segments are being filled.

I have checked the FM associated with the message type in WE20, WE57, and I haven't had any luck...
The issue is that the below highlighted segment is being filled with the wrong qualifier and I just want to know how these segments are filled:

This is the tech info wrt to this idoc:

I did find this FM online 'ISU_COMEV_REMADV_OUT' and maybe this has something to do with it but I just can't figure out how to debug this outbound idoc. So, can someone pls tell me how I can debug this idoc that is created through BCM?

Thanks in advance 🙂

Thank you, Miha... But there is no process code or FM associated with this message type/partner type in WE20... Is there any other way I can find the responsible FM?

Hello...

So, we were able to find the FM responsible for filling the outbound IDOC. It was FI_EDI_REMADV_PEXR2001_OUT. We found it in the payment run program in the F110 screen. But since it was a BCM process that is done in batches, we weren't able to debug by simply placing breakpoints. We had to place an infinite loop in a custom enhancement we happened to find and debug from there...

I think you'd be looking for function module ' FI_EDI_PAYEXT_PEXR2001_OUT', but it's certainly possible it's something else.

Thank you, Ryan... I had placed breakpoints in the FM but they weren't triggered... That's okay... But do you know how to debug and find the FM that is responsible for filling values into the segments of the Outbound idoc?
