I have gone through the thread below but it is not working for my problem. We have already allowed material and accounting document postings to previous period by setting in MMRV and OB52.
Here is a fact that has already happened in our S/4 PRD system. We posted 101 material document in June and reversed it with 102 in July, which was a mistake and that is not allowed by our finance department. We tried to post 101 again in July and in June, but 102 could only be posted in the same month as 101. The system indicated there was no stock available. Seemingly, the system did not verify the stock in June but July.
Now, how can we post 102 back to June? Much appreciated if you guys can help figure it out.
