Lock-entries in MM02 prevents booking from storage location to storage location

Hello everybody,

I have the following problem when acknowledging a TA (Transportorder):

Booking from goods receipt (LGORT 100) to high-bay (lgort 10). Because lock entries in the material master (eg. When a user in the MM02 is) the TA is indeed acknowledged, that the material is accurately recorded in the high-bay, but in inventory management remains a positive (WE lgort100) and a negative quant (WE lgort10 ) are on the goods receipt. If no lock entry exists when confirming the booking is fine and the two quants from the goods receipt immediately disappear.

The problem is but the material barrier is very often set in operation, as many staff there daily make changes and I would like to know how it is possible that the transfer is still performed correctly without which they must always be initiated manually afterwards (too many positions per day).

I'm thinking of something which, although the stock remains first on the 100, as described above, and is then adjusted on a regular basis as soon as the material lock is removed. Now Playing existed in store on the 100 getting bigger, although it is incorporated and acknowledged. the file in attachment shows the miss in the incoming goods. The 46 pieces are actually already in the high bay (LGORT 10), but are assigned to lgort 100 in the goods receipt.

Thank you, all the best.

    First thank you all for your help. Now i am a little bit more prepared to solce the problem!

    Got another question that could be the important key for solving the issue:

    We use in customizing the "Late Material Block". So that means that only when i press save, the material is blocked for a short moment..ok.

    BUT why are there three entries in SM12 (Overview lock entries) just when i open the MM02. That means for me the material is blocked since i opened the MM02. Isnt that a controverse to the configuration "late material block"? Whats wrong with my system, why did it block even when i open MM02? In that case the material is blocked for a very long time since the user closes the MM02, and that could be hours. seems pretty sure that i've got problems to confirm my TO when user block the material for that long time.

    best wishes, Jan

    • No it is not your case, I said late blocking has to do when people are posting movements for the same material. Late blocking will not resolve issues when somebody blocks the material with MM02.

      From my point of view is ongoing material maintenance not a usual approach. Of course it can happen that some fields need to be changed occasionally, or the material has be extended to a new plant, but this should not really lead to daily issues for WM postings

      Have you already analyzed what the people change in the material master, maybe they just use MM02 instead of MM03 when they display the material master

    How do you create these TOs?

    It looks like your process starts in WM, while the usual process starts in MM.

    • So, i made some Screenshots after doing MIGO (902 which is storage location 0100). Movement was 101.

      Now the Product is stored in 902 correctly (500 pieces). My next step now would be to create a TO in WM out of the TR to send the 500 pieces to main storage bin (which is 010 defined in customizing).

      After confirming this TO I would pretend, that the 500 pieces had disappear in the 902 and will now be in 010 main storage.

      I hope the screenshots will help you. I didnt create the TO at this time, just booked MIGO to 902 and the TR was created automatically. So the product is now on storage location 0100. The next step is the storage location movement, because the product goes from 902 (0100) to main storage (010).

    This is the LS26 after creating the TO from the TB (LT04).

    by the way, this link describe exactly what i am trying to do:

    Goods Movements from the GR Area - Warehouse Management System (WMS) - SAP Library

    The main problem is, when i lock the material with MM02 then, and only then, the negative quant and the prositive quant in 902 doesnt disappear.

    In SPRO, is this the right configuration for 0100 (Graphic SPRO attached)?

    Finally found the reason. The user didn't have the right authorization for the posting from "lagerort to lagerort", thats why it stucks. Thanks for all your supply.
