Two consignment vendors during stock determination

Hi all.

Under customizing related to stock determination I included to have prirority own stock over consignment (for both MM and WM).

My question is how is the stock determination performed in consigment when there is stock of two different vendors for the same part?

I read in Help-SAP that stock determination is applied first in MM and then the system forwards this data to WM (WM stock determination int his case is not possible). There is no sort for prices, nor quantity.

In my particular case, I have two steps for production process (REM); in this case no own stocks exists but consingment for two vendors:

1. In MF60 (movment 319) TRs are created (and then TOs) to move materials into 100 storage type. When 2 different vendors are managed I thought that the system would transfer the older quant but when both stocks are in the same storage bin with the same GR date I don´t understand exactly the stock determination made.

2. MFBF is performed to consume all components (movement 261K); here stock determination is executed again first in MM but I don´t know exactly how the system chooses the vendor

Could it be the criteria different in the first step rather than the second one, so I move physically stock from one vendor but informatically consumed the other one? is there a way to avoid this?

Any clarification will be wellcomed!!!

    1) Please read OSS note 365570.

    For instance:

    - WM dominates

    Warehouse Management System WMS picks the necessary quantities independently of the stock category of the materials and only takes the picking strategy into account that is defined in the WMS here (for example, FIFO).


    In the stock determination header table you define the priorities of:

    - item table (V_T434K-RAPOS)

    - price (V_T434K-RAVAL)

    - quantity (V_T434K-RAQUA)

    Based on these priorities the system will determine a number for each relevant stock item and then sort the internal table (check include: LMDBFFS0).

    Additionally you can use user exit EXIT_SAPLMDBF_002 (XMBF0001) to influence the sort sequence.

    So, the vendor id itself has no importence in standrard system from stock determination point of view.

      Thanks again.

      I asked development team and we will try to launch report RLLQ0200 after TO confirmation.

      I am going to close the issue but before just one commnet. I agree with you when you point "this "older quant" statement in your description is not true in itself, it only might be true depending on your WM and stock determination settings" but the I found a mistake because for the same storage bin in the same storage type, two different quants for differents vendors with different GR date, it was determined the newest quant to be moved into production area. The priority was included with value "2" but changing into "3" it didn´t determined either the older quant.

      Best regards.
