An user
reported he found in MB51 two material documents associated to the same
reservation.
The
reservation was created (tx. MB21, mov type 201) for 10 UN. In MB51 I found two
materials documents associated to the reservation, 10 UN each! There is no a
cancellation (I verified through MBSM).
I found the
material documents were posted by different users with 26 seconds of difference.
I
replicated this case with two SAP sessions. I called transaction MIGO in each
session and posted a good issue 201, and immediately I posted a second good
issue 201 for same reservation. System posted both documents!!!!! I assume it
was possible to post the second one because field RESB-KZEAR was blank at this
moment.
Then I
called transaction MIGO in two sessions again, and posted two good issues 201
for the same reservation, waiting a prudential time between both postings. System
issues message M7 064 “Document & does not contain any selectable ítems”. I
assume in this case, system “had enough time“ to set field RESB-KZEAR as X.
It is possible
to block object “reservation” during posting to avoid this behavior?
