Stock material difference between MM and WM

Question

Good morning, i have a question about the difference between Stock material from MM and WM.
My customer, told me about difference in material stock in tables MARD and LQUA.
He told me that stock material in LQUA is greater than in MARD, because some users didn't work correctly.
Since correct stock is in MARD table ( and not in LQUA), my question is: is there any standard solution (transaction ,program, or others ecc.) to make equal the quantity values in both tables?
Thank you in advance for your cooperation and attention,
Francesco

Francesco,
Have you checked the warehouse activity monitor (transaction LL01) to see if there are any incomplete documents there?
In general, an Invneotry Movement (receipts, issues, transfers, etc) will trigger a WM movement via transfer postings and  transfer orders.
The best way to habdle this may be on a case-by-case basis, and use the appropriate transactions to correct your issue.
<B>Example scenario:</B>
User does a goods issue (reduces MM quantity). The transfer order may not have been created or may not have been confirmed. In either case, WM quantity is not reduced, causeing WM to be higher than MM.
If the TO was not created, there iwll be an open transfer requirement - try processing it in the foreground.
If the TO was created but not confirmed, try confirming it.
