Summary

0011268: MRP: Purchasing plan is showing unexplainable negative quantities for Purchase Order lines that were already received

Description

In the BFT we have an exercise to execute the Purchasing plan. The product is Hammer and it's a product we don't use in any other exercises. However, the student apparantly had been playing around and had entered Purchase Orders and Goods Receipts for the Hammer. When running the Purchasing plan, the outcome looked really strange (see snapshot): Purchase order lines were showing up as a negative quantity instead of a positive quantity. I thought that maybe too many quantities had been received by the goods receipt, but that was not true.The exact quantity of what was on the purchase order was also on the goods receipts, so the Purchase Order should not have appeared at all.

Information:
Purchase Order 800024 for example: 15x on line 10, 15x on line 20 (total 30x)
For that PO, there is goods receipt: 10000030 for 10x on line 10, 10x on line 20 and 10000031 for 5x on line 10, 5x on line 20. So this totals to 30x aswell.
So the whole Purchase order was received and should not be showing up at all on the outcome of the MRP.

Steps To Reproduce

MRP || Setup || Planning method
to look at Pending Purchase Order, Pending Sales Order

update the Hammer product with the planning method and safety stock level, enter a Purchase order and a Sales order for hammer.
Obviously in this case there was already previous activity on the Purchase orders with goods receipts.
