Check lot number repeated
We are on some since few years. At that time, In check lot maintenance in SAP (FCHI), we defined check lot from 110001 to 110100 for House Bank SBIH and Account Id: SBI1. This lot was fully utilized that time only.
Now yesterday for same branch (i.e. same house bank and account id) we got same check lot (with same check number range).
Now when i entered the data in FCHI, SAP gave error that "Check number are overlapping"
I thought of adding one prefix to the new check lot. But management didn't accepted it. So i need to know how this practical problem of entering repeat check lot number will be entered in FCHI.
Is there any archive facility or something (in standard SAP) which will allow the same?
