Posting Change Notice processing issue.

996 Views

I encountered a issue with processing Posting Change Notice (PCN) recently. Basically, the problem is that two TO got created and confirmed for the same PCN almost at the same time (1 second interval) by the same userid or two different userid. This leave the PCN with "Partially processed" status and could not be cleared out because, when trying to change/display the PCN, the system throws a error message saying "Open quantity is less than the posted quantity" (two TO confirmed so the posted quantity doubled in PCN).

Here are some background info

The PCNs were created from MB1B from IM. The IM movement type invovled were 321 (for post Q stock to UR stock) and 411 (for withdraw from consignment stock), and the corresponding WM movement type were 321 and 309 respectively.

Example

Here is a example, the following two TOs were created 1 seconds apart by two different users against the same PCN.

TO number Item Material S C Tpe Source bin Source t CS Conf.date Conf.t. User

Plnt Created on Time Tpe Dest.bin Dest.tar Co Mov.ty Movmt SLoc

If the two users were trying to process the same PCN at the same time, either one of them should have failed if the other one created the TO successfully. Also, the TO numbers are not even close to each other with considering they were created almost the same time.

I have another case, the two TOs were created by the same user at the same time against the same PCN.

Thanks for your help in advance.
