No RSINFO Idoc comming from ECC

Hello all,

We're being faced with a rather strange problem:

When extracting (master) data from ECC to BI, the request remains yellow in RSMO. The reason for this is that there seem to be missing messages (requests received, number of sent records, selection completed). These should come via a RSINFO Idoc from ECC, but this Idoc is not sent at all. In the partner profile on both BI and ECC, this Idoc is entered right.

A connection check from RSA1 is successful, and we've already tried reactivating and restoring the source system. Both actions did not solve the issue.

Can anybody shed some light on this problem? Thanks in advance!

Kind regards, Wilbert
