Fixing a BOM 

Use

The system fixes a BOM if it is part of a Baseline. During fixing, it is determined that all BOM change statuses documented in the Baseline can be reproduced later.

Features

BOM fixing is controlled by Engineering Change Management. If you freeze a BOM in a Baseline, it has the following effects:

List of the Change Numbers

For each BOM, the system cumulates a list of change numbers. In this list, the system includes all change numbers that you have used to process the BOM and that you have released up to the point in time when you froze the Baseline.

You can display this list in the structure of a Baseline by clicking the right mouse button on the node with the symbol .

Indicators in Object Management Record

In each object management record that you have used in the processing of the BOM, the system sets the indicator Baselined. If this indicator is set, the BOM can no longer be processed with reference to this change number. Furthermore, in this change number, you can not carry out any more date shifts for the object contained in the Baseline.

Change Number is Obligatory

As long as a BOM is a part of a Baseline, it automatically requires a history. This means that you can only process this BOM with reference to a change number. Therefore, you can also not change the BOM without a change number if you use the authorization object C_STUE_NOH.

From the time you create a Baseline, you process all BOMs contained in the Baseline only with reference to the ECR/ECO.
