Validity Period in SAP PP

The system uses the validity period you enter for the BOM header to determine which items are valid. You can restrict the validity period for displaying the BOM.

On the initial screen, you can use the following four fields to define the validity period:

• Change number

• Valid-to date

• Valid-from date

• Revision level

The following table shows which entries you can make to define validity.
