IR/GR accounting doc not posted

[Former Member]

Hi Gurus,

We have a strange situation. Existing process we have our SAP integrated with other systems and we receive RFC call to post GR and IR for POs. Even if IR comes before GR, it works fine and postings are correct.

Now we added new system (S4) which will send GR/IR. We added some new GLs for posting IR accounting docs. When GR comes first followed by IR, it works fine. All correct GL are posted.

When IR is posted before GR, no accounting doc is created for IR and GR. Can someone let us know why in this situation is behaves like this?

Further, we are trying to reverse IR and GR and post GR first followed by IR, but we are facing following issue-

1. IR reversal not possible in MR8M as no accounting doc exists

2. GR is reversed creates accounting doc, which will cause mismatch as there is no accounting doc in initial place.

How to we solve this? We have around 15-20 such POs in production.

Quick help will be appreciated.
