can you give a proof that this IM stock should be in WM too?
are these 5 in the same location as the 10 and 3?
Is it a new case or something left from the very beginning of your system, e.g. from times before you activated WM?
Do you use Quality Module and inspection lots, or just the "post in to quality stock" indicator?
This makes a difference in the solution, so it is needed to know to give a straight answer.
Why wont you use LX23?
It is the designated transactions to clear inconsistencies.
