In material requirements planning (MRP), the discontinuation data in the material master record transfers dependent requirements for a material component that is no longer in stock (in sufficient quantities) to a follow-up material. You can also specify a follow-up material for an item in a BOM. The data for this is maintained as Discontinuation data.
The follow-up item specified in the BOM overrides any follow-up material maintained in the material master record.
Multiple levels of discontinuation data are not supported. Once a material master record (MRP data) has discontinuation indicator 1 (simple/parallel discontinuation) and a follow-up material, you can no longer enter the material as a follow-up material in a BOM.
Prerequisites
Before you can use discontinuation, the following must be true:
You can define discontinuation data for the following item categories:
You cannot define discontinuation data for the following item categories:
You can only define discontinuation data for a stock item or variable-size item that is not assigned to an alternative item group.
Once you have maintained discontinuation data for an item, you can no longer assign the item to an alternative item group.
Discontinuation is not supported for co-products.
