System is not considering open reservations at the time of next MRP Run

115 Views

Hi,

In our business process, subcontractors are defind as Vendors in the SAP system and materials will be provided / transfered to these subcontractors in the SAP system through Subcontracting route (541 movement type). Now, business wants to 'Monitor' the stocks at these subcontractors, so that always subcontractors should have the Optimum stocks at his location. So to monitor the same, business wants to have the MRP / CBP process in the SAP system.

To run the MRP for all these Subcontractors at each material level following configuration and Master data is maintained in the SAP:

Business is having around 10 plants in the SAP system and all these plants are defined as MRP Areas in the SAP system to run MRP. Along with this subcontractors (100 Subcontractors) are defined as MRP Areas (100 MRP areas) in the SAP system and each MRP Area (subcontractors) are mapped in the MRP Area configuraion according to the respective above mentioned plants in the SAP system.

At the time of running the MRP for these MRP areas in the SAP system based on Re-order point and Max stock level (both at subcontractors MRP Area and Plant MRP Area Level), system will consolidate the requirement from all the subcontractors MRP Areas (Transfer Reservation) to at plant level. From plant a considering all these requirement + warehouse buffer stock, a Purchase Requisition will be raised to procure the material from other plant or from external vendor.

Suppose, if the requirements of the previous MRP run are not fulfilled in the SAP system, and if MRP is run again in the SAP system at both Subcontractor MRP Area and Plant MRP Area Level, the system will delete the Previous "TRANSFER RESERVATIONS" and Recreate the new one. The problem here is suppose eventhough the Transfer Reservation requirements are partially fulfilled, a new reservation is Re-created in the SAP system in the next MRP run and this will create the Incorrect results in the MRP results/requirements.

So, can you please suggest what can done for this problem?

Thanks & Regards,

Pavan
