RFC receiver adapter - not updating ECC

Hi experts,

I have a very peculiar problem.

I am working on a File to RFC scenario on PI 7.11.

There is no error reported in SXMB_MONI or on RFC adapter in CC monitoring. But the RFC does not update ECC table.

I have done this without using a BPM. Also I am not mapping the response of the RFC. I also put a breakpoint in ECC for the same user that is used in the CC configuration, but it does not stop.

Could someone help me troubleshoot this issue. I have checked the RFC setup and it is fine.

Thank you.
