Looking for table that links a PM Reservation to a MM Purchase Requisition

Answer 1

Hi,
    Typically the way most SAP systems are configured, there are two scenarios here:
1. The component reserved in the PM order is item category 'N'. This is a non inventory item and must be directly procured for consumption against the PM order at the point of goods receipt. In this case no reservation is created and instead a requisition is directly created (in table EBAN) and the requisition is account assigned directly to the PM order (in table EBKN - field AUFNR).
2. The component reserved in the PM order is item category 'L'. In this case no requisition is directly created, instead a reservation is created against the item in stock (in table RESB). If there is sufficient stock of the item already then the item is consumed when it is goods issued to the PM order from stock using MIGO and there is no requisition created. In the event that there is not sufficient stock of the item for the reservations that exist, when MRP is run, a requisition will be created to replenish the stock, but this requisition will not be assigned to a specific PM order as it could be replenishing stock of the item for several reservations which are all for different orders. So in this scenario there is no direct link from the reservation generated by the PM order to the requisition.
