Discontinued products MRP4

Dear SAP-experts,

A Material is discontinued at our company, the setting in MRP4 has been changed as can bee seen in figure 1:

figure1: MRP4 5090-0004-0008

the effective out date has been set for a while now (01-11-2013). However when a demand is created for the product SAP always look at the current available stock (as can bee seen in the figure 2), and conclude there is still enough available. In the example below the following demand for the material was needed:


So the demand of 22.09.2014 (76 pieces) could be satisfied by material 5090-0004-0008

But for the demand of 24.09.2014 (126 pieces) only 2 items are left however the system still looks at the current stock level and concludes that 78 pieces will be taken from material 5090-0004-0008 and the rest (48 pieces) is taken of the new material 5001-0000-0025 (figure 3). The same applies for the demand on 29.09.2014 and 15.10.2014

figure2: MD04 5090-0004-0008

figure3: MD04 5001-0000-0025

How can I manage that for the demand of 24.09.2014 (126 pieces) the system only uses the 2 pieces that are left of material  5090-0004-0008 and that the rest of the demand (124 pieces) is set on material 5001-0000-0025.

So the demand for 5001-0000-0025 of 24.09.2014 should be set to 124 instead of the 48.

The note suggested by Jurgen is relevant in this case.

As it is stated on the note, the discontinuation for a production order reservation is carried out during the components availability check, not by MRP.

If the reservations are no being redirected to the follow-up material, that's because the ATP check can still confirm the quantity for this component.

Checking the screenshots, I have noticed that all the reservations higher than the stock quantity were correctly redirected to the follow-up material. Maybe it's because, on your scope of check customizing, you do not consider reservations. That way, system always confirm the component quantity if there is enough stock.

Please review your scope of check customizing and include reservations.
