Multiple production orders are generated for same requirement

14 Views

hello guru's

For a MTO (make to Order) scenario, where the Material requirement quantities are generated from Sales Orders.

Ex: Sales Order created for 500 Qty.

I had run the MRP using MD03 with the following parameters

Processing key NETCH Net Change in Total Horizon

Create purchase req. 1 Purchase requisitions in opening period

Delivery schedules 3 Schedule lines

Create MRP list 1 MRP list

Planning mode 1 Adapt planning data (normal mode)

Scheduling 1 Determination of Basic Dates for Planned

System had generated Planned Orders for Qty 500 and these are converted to Production order for Qty 500 for which the Purchase Order for 500 are created.

Goods receipt of 480 has been made against the Purchase Order for the Ordered 500 Qty.

When I re-run the MD03 the system is generating the new Production Order Qty 0f 20 which is not supposed to be as this 20 Qty was already part of the existing Purchase Order and yet to be delivered .

Could you please explain me why this is happening?

regards
