Component Scrap

The component scrap is defined to take into account all faults that occur before the component is put into an assembly (material provision scrap).

This is possible in the following situations, for example:

A percentage of the parts to be assembled is already defective on delivery.

Losses occur during storage.

Component scrap only affects one component of an assembly. When you explode the BOM, the system increases the quantity of that component by the Scrap quantity calculated.

In product costing, this value is used to determine excess consumption of materials or activity.

There are two ways to maintain component scrap:

In the BOM on the Item detail screen: general data under Quantity data.

This component scrap is only relevant to the individual BOM.

In the material master record on the MRP 2 screen under Requirements explosion

If the same component scrap applies to a material in a number of BOMs, we advise you to maintain the component scrap in the material master record.

If the component scrap for a material is the same in all BOMs, maintain the scrap in the material master record.

Calculating scrap

Component scrap only applies to one component.

The component scrap maintained for a material component in a BOM overrides the component scrap maintained in the material master record. If you maintain component scrap in the BOM, the system always uses the component scrap in the BOM to calculate component quantities.
If you do not maintain component scrap in the BOM, the system uses the component scrap stored in the material master record to calculate component quantities.
