Use
In MRP, the discontinuation functionality is used to transfer dependent requirements of a component to one or several follow-up materials, if the requirements are no longer covered by stock. You can also define a follow-up material in the bill of material.
The follow-up item defined in the bill of material overrides any follow-up material maintained in the material master record.
You cannot maintain discontinuation data for text items or class items.
Features
A distinction is made between the following:
You assign a follow-up material to the material that you wish to discontinue. The missing requirement quantity is then automatically assigned to the follow-up material.
You can assign a follow-up material to a material in the material master and in the bill of material.
A main material (main item in a
You can only maintain items of parallel discontinuation in the bill of material.
Requirements for Discontinuation
The following requirements must be met for follow-up materials and parts to be discontinued:
The discontinuation functionality does not work over multiple BOM levels. This means that if the discontinuation indicator 1 (single/parallel discontinued part) is set in the material master of a material, this material can no longer be entered as a follow-up material in the bill of material.
Discontinuation Data
You enter the data for discontinuation on the General data tabstrip. You maintain discontinuation data via the function key Discontinuation data.
In a dialog box, you can display or maintain the following data for the item:
This freely-definable character string groups together related discontinued items of a bill of material.
To carry out a parallel discontinuation, you need to identify the main item to be discontinued in the bill of material and the subordinate item to be discontinued using the same discontinuation group (see example below).
This freely-definable character string groups together related follow-up items in a bill of material. The follow-up group also determines which discontinued items this follow-up item replaces.
If this indicator is set, the material is defined as ‘to be discontinued’.
Examples for Discontinuation
The following examples illustrate how discontinued and follow-up items are used:
Simple discontinuation
In this case, Item 0010 (material M-2) replaces Item 0010 (Material M-1). There is no need to define a discontinuation group or a follow-up group.

Parallel discontinuation
In this case, the discontinued items 0010 (material M-1) and 0020 (material M-2) are replaced by the follow-up item (material M-3).
Material M-1 is the main material to be discontinued (discont. type 2), material M-2 is the subordinate material to be discontinued (discont. type 3), and material M-3 is the follow-up item (discontinuation indicator 5).

Parallel follow-up
In this case, the discontinued item 0010 (material M-1) is replaced by the follow-up items 020 (Material M-2) and 0030 (Material M-3).
Material M1 is to be discontinued (discont. type 2), materials M-2 and M-3 are the follow-up items (discont. type 5).
