Lot of our decrease and cancel Po suggestions are for parts with minimum order quantity. Seems like MRP is ignorning the minimum order quantity while it is looking at supply, so it ends up creating cancel and decrease suggestion. Is there are any workaround so that MRP acknowledges the MOQ.
I believe those suggestions are due to MRP only comparing the supply with demands from jobs or sales orders. So it will always create the cancel/decrease suggestions for any supply resulting from MinOrdQty (and MinQty).
When systems are generating a lot of suggestion “noise”, you might be able to reduce the amount of unwanted suggestions by playing around with your “planning” settings. e.g. Reschedule In/Out Deltas found in part classes and part masters.
