Inconsistent stock category WM and MM

Hello Experts,

We have situation where on IM level (MMBE) 269 pcs of material under Q stock.

But in WM (LS24) 269 pcs are in S stock. If we make UD in QM. Stock transfer to unrestricted in MMBE. But still available as S in WM .

Could you suggest if it is the known problem?

Thank you in advance.

    It is a known problem when users are not properly trained how to deal with posting change notices.

    Check the development of the situation by looking into MB51 movements

    then compare it with your PCNs in LU04 (status open, partially posted, completed)

    • That`s correct Jurgen. Sorry for usefulness screenshots. But there are a lot of movements for this batch. I can send Excel sheet from SAP MB51. Or can we make small discussion in some private chat?

    As Juergen has explained, system is working as defined. You need to understand what is the mechanism called as posting change notice. Posting change notice is generated either your stock category is altered( example Quality to unrestricted 321 movement).

    SAP says:Posting changes (from the WMS viewpoint) are postings in inventory management that, because of their movement type, can lead to a reduction in one stock and simultaneously an increase in another stock, where both stocks are in the same warehouse number. As a rule, these postings are executed in WMS through the posting change area. So, you need to view the posting change in LU04, and confirm transfer order generated.

    • Hello Shailesh Mishra. Thank you for the explanation. I got that after MM movement there generated negative stock (of the 1 stock type) and positive (of the 2 stock type) and in LU04 we can make situation clear by TO`s. But here is situation where in MM level I have stock 269 pcs under Quality Insp. (Q) and in WM i have stock 269 pcs under S stock type. Only these without any negative quants and other stocks ever.
