Definition

Scrap of a material that is expected to occur during production if the material is a component.

Use

Component scrap is used in MRP to determine the input quantity of the components. When you produce an assembly with this component, the system has to increase the component quantity to enable you to reach the required lot size. You can enter component scrap in the BOM item or in the material master. When exploding the BOM, the system increases the input quantity of the components by the scrap quantity calculated.

The unplanned component scrap is shown as input quantity variances at period-end closing in Product Cost by Order and Product Cost by Period,.

NoteFor components in an assembly with

assembly scrap, the following applies:

The system first calculates the assembly scrap, then the component scrap. The scrap quantities calculated are added and the quantity required is increased accordingly.

You can maintain component scrap:

  • In the
BOM item

In this case, the component scrap is only relevant for this particular BOM.

In this case, the component scrap is relevant for all the BOMs that contain this material.

Note

If component scrap has been included in the BOM, the value entered there applies. Otherwise, the value entered in the material master record applies.

If you maintain component scrap in the BOM item and in the material master record, the entry in the BOM takes priority.

Component scrap does not affect the production periods.

Example

Example 1

For the component raw material C of semifinished product H, an assembly scrap of 10% has been entered in the material master. The system thus costs 100 pieces of the finished product with 275g (250 + 10%) of raw material C, not with 250g. The component scrap is 25g.

For the component raw material X of the finished product, an assembly scrap of 10% has been entered in the material master. The system costs 110 pieces of raw material X (100 pieces + 10%) The component scrap is 10 pieces.

Example

  Example 2

For the finished product, you have entered an assembly scrap of 10% in the material master. For the components raw material X and raw material C, you have entered an assembly scrap of 10%.

Example

  Example 3

For the finished product and for semifinished product H, you have entered an assembly scrap of 10% in the material master. For the components raw material X and raw material C, you have entered an assembly scrap of 10%.
