For us, each production order will have some planning space entered as queue times in D365.

Production is allowed to start order at any date within interval StartDate - EndDate, as long EndDate is kept.

Our strategy is to create pick work as late as possible, very close to the actual picking time.

Normally we also have a “Raw material picking date = Start date for first operation”. This is to ensure purchases are made and received ahead of production order start.

All BOM items are reserved but not yet picked. As start date often is days ahead, picking that early is not feasible because of not enough space to place goods ahead of time.

Standard behavior will generate a delay for a production BOM-line if the raw material date (for the production BOM line) has passed and the material is not consumed on the production order (posted picking list journal). Pegging information from the MRP is not taken into consideration.

Suggested behavior: If production order status is Released or higher - only generate a delay if BOM-line is not reserved and BOM-line is delayed; (delayed = refill of BOM-line has a planned stock date later than raw material date)

Better options on coverage group (or similar) to control delay behavior here is what we are looking for.

This was possible to extend with Classic MRP to support this scenario, but we have not found a way to do this with Planning Optimization. With current behavior it will generate a massive amount of action messages that are just noise.
