Engineering Change Management: Validity Types for Bills of Material


Previously, you could define the validity of an object change using the valid-from date of a change number. The change becomes valid on the valid-from date.

As of Release 4.0A, you can use new validity types to define the validity of changes to BOMs.

The following new validity types are defined in the standard R/3 System:

You can define the upper and lower limit of the validity period of an assembly.
You can define the validity of an assembly in terms of the serial number of a finished product.
This is especially useful if the change to a finished product is subject to strict access restrictions.
You can use validity type Serial number to define the validity of a change as follows:

Company-specific validity types
In Customizing, you can define company-specific validity types.

In this step, you activate the new validity types.

Further notes

The new validity types are only supported for BOMs in this release. Once you have defined a change master record with a new validity type, you can only use it to change BOMs.
