Unused material in the production staging area WM/PP

Hi

I've an issue on how to handle the staged materials for a process order. The current process is that after the process order is released, WH staff stages the material for the process order based on the TR (TO from LB13). Some of the raw materials staged are in excess qty than the requirement. As an example, acid required for the order is 10 liter, but it can be only staged in 16 liter drum. The process order consumes 10 liters as a backflush and 6 liters left over is not returned to the warehouse but is consumed in the next process order. The question is, I want to consume the left over 6 liters acid into the next process order and this new process order requirement of 10 liters should be met by consuming left over 6 liters (again as a backflush or by any other method other than manual issue to the order) and the TR for the new order should have a requirement of only 4 liters. Can somebody suggest a way this can be achieved by SAP standard method or by using any user exit etc? Your help is greatly appreciated.

Thanks

BElfie

  • Does this not happen automatically already as explained in the docu?

  • Jurgen: I followed the document you suggested and I was able to create an automatic TO for the process order. However, when I close an order (TECO) after partial completion leaving unconsumed components in the staging bin, the TO for the next process order does not consider the existing stock in the staging bin (ie., no quantity reduction occurs). Here is my set up, pl. let me know if there is something I'm missing - I'd really appreciate your help in resolving this issue.

    (1) Control cycle for pick parts, with fixed bin (stor type 100 and bin FEED1)

    .(2) Mvt type 319 set for auto TO creation,

    (3) OMK0 - prod sched profile set for auto TO creation, WH No. set for complete staging and deactivate qty reduction is NOT set and qty reduction is set as 'blank'.

    Thanks

    Hi,

    Could you please refer this Wiki page which provides the details about all the userexits available during Transfer Order processing which would be checked via debugging:

    Based on your requirement, you can choose the relevant enhancement.

    Hello Belfie,

    Greetings!

    Quantity reduction is configured in the WM customizing for the PP interface. This can be seen at the following menu path:

    SPRO -> Logistics Execution -> Warehouse Management -> Interfaces -> Define Production -> Stor. Typ

    Here the system is configured to automatically allow quantity reduction. For quantity reduction, the system checks the destination storage bin in production for unrestricted stock to prevent unnecessary transfers out of the warehouse from taking place. If there is stock already existing, then the requested amount will be reduced accordingly.

    When carrying out quantity reduction, the system checks for open reservations for that material / batch in table RESB. Taking this quantity plus the available quantity in the production staging bin, the newly requested quantity can be reduced accordingly.

    Quantity reduction takes into account the existing bin quantity and open quantities being requested in system.

    For further information regarding this and the customization please refer to SAP Knowledge based article(KBA) 1933100.

    Regards,
    Renuka

    • Hello Renuka

      Thanks for the reply. My config is exactly as you described (OMK0 > stor type is set to blank and my control cycle has pick parts and fixed bin). However, every time I create a new process order, the new transfer order from the TR does not consider the stock in the staging bin. Yes, the previous process is TECOed before the new process order is released. What am I missing or is there something else I should to enable this qty reduction to kick in? Pl. let me know.

      thanks

    There is a very important sentence in this KBA: "the system checks the destination storage bin in production for unrestricted stock to prevent unnecessary transfers"

    How is your destination storage bin for the new TO, and in with storage bin is the excess stock from the TECOed order?

    • Hello Jurgen

      The left over stock from the previous order is in the storage type 100 and bin FEED1. The new TO does not take the available stock in this bin into account and creates requirements for the total quantity. Is there anything that I should check or make changes to? Pl. let me know.

      thanks
