Stock transfer and external requisition for same material

[former_member452116]

Hello

The requirement is as below.

MRO/Spare parts for preventive/breakdown maintenance are planned via Min-Max MRP and procured from vendors. These materials are common across plants. However each plant procures independently, this leads to excess inventory org.wide. So there is a requirement to first request internal stock transfer before procuring externally for managing inventory levels better.

Let me paint a scenario

Component #123 | Receiving Plant : AAA1

Regular vendor for component #123 at plant AAA1 is VENDOR1

Component #123 stock also present in plants BBB1, CCC1, DDD1

BBB1 = 30 EA

CCC1 = 40 EA

DDD1 = 30 EA

Now, Say there is a requirement for 150 for component #123 in plant AAA1

The expectation is MRP should create the following requirement elements,

Stock transfer requisition for 30 EA with supplying plant BBB1

Stock transfer requisition for 40 EA with supplyin plant CCC1

Stock transfer requisition for 30 EA with supplying plant DDD1

External Purchase requisition for 50 EA with vendor VENDOR1

To my knowledge, this is not possible via standard set up. Is there a BADI that can help achieve this requirement?

Hello sriramkittu169

I understand. You may try quota arrangement and see if it helps you. Just make sure to post back the results for the benefit of SAP Community.

However I'd say quota management will not work for you. It allows to assign different sources of supply e.g. delivering plants but it will not consider the stok availability in the plants.

The more I think about your question the more I'm convinced that your process design if flawed and that's way you are having problems. Plants are planned independently by MRP, the rules of MRP planning and demand plan are maintained on plant level (I'm skipping MRP areas intentionally here). Therefore whatever stock you keep in each plant it is there to cover actual or planned requirements. Now if as in your question you move stock from plant BBB1 to plant AAA1, then you'll end up with too few stock in plant BBB1. Notice that you'll be moving stock from BBB1 that should be there to cover requirements. If you need to do that on regular basis it means that your MRP planning is wrong and you are holding to much stock. If you want to move the stock only occasionally you can as well handle that manually.

I agree with your assessment. My line of thought was to use splitting quota and influence the order quantity calculation. basically influence the number of sources and replace the system calculated quantity for these sources with stock available at supplying plant. This may be a core code modification.
