using a reorder procedure for inter plant stock transfers… whats the lead time?

Yes, you can use a reorder point procedure for inter-plant stock transports, but be careful what you put into the lead time.

When you source materials from one of your own plants, your lead time (in the field Planned Delivery Time  (in the delivering plant) should be the time it takes from the issue in the delivering plant until it arrives at the receiving plant. The only question is: Can the delivering plant issue right out of available stock?

If the delivering plant does not keep the product in stock but has to procure it also, then the total lead time until it arrives in the receiving plant will increase dramatically. But if you put that total time into the PDT, you will ask the delivering plant to issue way too early. Unfortunately the TLRT in MRP3 does not work with procurement indicator ‘F’, so what can you do?

I know people have played around with source lists and info records but if you want to use an automatic reorder point calculation (VM or V2) you need to put the total replenishment lead time into the PDT, because that is what the reorder point calculation uses. So you are stuck with a manual reorder procedure (VB or V1) and you will have to include the entire total replenishment lead time in your spread sheet calculation.

The SAP Add-On Tools (MRP Monitor and Reorder Point Simulation) give you added possibilities: Since the MRP Monitor also performs an EFG classification for lead time – and lets you pick the TRLT from the MRP3 screen – you can build a list of items which are feasible for an auto-reorder procedure (X – consistent consumption, C – low consumption value, E – short lead times). The Safety Stock and Reorder Point Simulator then lets you calculate and simulate various service levels for optimized reorder points and safety stock settings… and allows for a mass update of the policy.

      Hi, can you explain how this would work consider you would play with source lists and inforecords?

      Thank you in advance for your support.
