Issue description
If a production order was created from the Inventory Planning Display (AM400000) form for a non-lot/serial tracked item or a lot/serial tracked item with the When Used assignment method, there was a mismatch between the Qty. to Produce in the Summary area and the Quantity column on the Line Details tab on the Production Order Maintenance (AM201500) form (see the following screenshot).

On the Inventory Allocation Details (IN402000) form, the system displays incorrect allocation for the production order that was created (as the following screenshot shows).

In this scenario, when the quantity in the Quantity column on the Line Details tab is less than the quantity shown in the Qty to Produce box in the Summary area, the demand reoccurs on the Inventory Planning Display (AM400000) form, and this results in incorrect MRP Planning.
