Diagnosis
You want to change a BOM group with reference to a change number.
In the change master of this change number, the following indicatorsfor controlling processing of individual object types are set:

• Indicator: management record required for each object

In the change master for this change number, there are no objectmanagement records which have been entered manually.

• Indicator: object management record generated

To generate the object management record, the system needs the data forthe material, the plant and the usage. As no BOM of the selected BOMgroup has yet been processed with reference to this change number, noobject management record could be generated.

Procedure
If you want to change the BOM group with reference to this changenumber, enter the data for the material, the plant and the usage.
If you do not know this data, you can first display all the BOMs whichbelong to the BOM group by entering the BOM group. On the BOM headerdetail screen, you see the data you need.
