PO is not considered by MRP.

Hi friends,

For certain materials, we see that manually created POs are not being considered by MRP. Those POs will get exception message 20 (cancel), and for the same date & qty, MRP-run will create new purchase requisitions. Any clue as to what all things might be resulting in such MRP behavior ? (The BAdI-Active check-mark is NOT there, so there is no BAdI logic affecting this).

Thanks,

- Chetan

    Sorry for an error in my problem description. This material has MRP type PD, Safety stock = 0, Strategy = 40, Plnd Del time = 7

    MD04 shows as below:

    09/04/09 Stock 0

    09/03/09 CusOrd 2- 2-

    09/08/09 POitem EM-20 2 0 (my question is why this PO got EM 20, and next PurRqs created ?)

    09/11/09 PurRqs 2 2

      Chetan,

      You are describing standard functionality for PD under purchasing. SAP 'knows' that the existing fixed element (your EM-20 PO) cannot meet the requirements date, so it creates a new proposal. Unfortunately, due to your planned delivery time, it cannot create the proposal any earlier than the Sept 11 date..

      I suspect you have not maintained any entry in the rescheduling horizon. If you have not, do so now. You can change this behavior by altering the rescheduling horizon settings (OPPQ for plant, or if you are using MRP Groups, OPPR). In your case, you probably will want to start with a short horizon. You can also optionally increase the tolerance setting.

      For more info, see [OSS note 25388|https://service.sap.com/sap/support/notes/25388]

      Rgds,

    1. Check in material master MRP4 view, if indv/coll filed in "2". This will combine requirements.

    2. Check the requisitions created by MRP, are they sales order specific "E"? If yes, then the manual PO's you are creating could be standard stock PO's, and this is causing the problem. You will have to create manual PO's assigning them to the sales order like items.

    Please also check if the SLOC (EP SLOC) in MRP View 2 you specify are considered for MRP.

    If in the setting this EP SLOC is excluded from MRP, the PO material you created will not be considered in MRP.

    Thanks
