Hello,
I’m in 23R1 and seeing some unexpected behaviour with MS Level 1 parts when I run Site level MRP.
I have 20 Manufactured parts that are MS Level 1 parts. Create S/P is set to create S/P Entire Horizon and when I run the MS calculation, everything works as I expect and Shop Order Requisitions are generated.
If I then run selective MRP based on the Planner these parts share, the demand flows down and MRP generates Purchase Requisitions for the component parts.
However, if I run MRP for the entire Site, MRP generates a handful of Shop Orders for the MS Level 1 parts. I did some investigating and this seems to happen if the on-hand quantity is below the safety stock.
If I Re-Run MS after this, the MRP generated requisitions are then deleted.
Is this a bug? The parts are top-level sales parts and not in any other structures.
Requisitions Generated by both MS & MRP for the same part:
