For some object types (for example, BOMs, documents), you can use object management records in the change master record to control changes to individual objects. An object management record documents changes to an individual object. You can also set an object-specific valid-from date and status network.

BOMs that belong together in a BOM group, are stored under one internal BOM number. Only one BOM appears in the object overview.

This is the case if, for example:

• A material BOM is extended by one variant

• A material BOM is allocated to an additional plant

In the object overview of the change master record, you see the first BOM from the BOM group that was entered as an object for the change number.

Starting from the General object overview or a special overview for BOMs (for example, the Material BOMs overview), you can display all the BOMs in a BOM group by choosing BOM list, as shown in the following graphic.

The BOM list contains all the BOMs in the BOM group. The system sets the following indicators as appropriate:

• BOM exists A BOM exists for the material displayed.
• ObjM.ex An object management record exists for the material displayed.

You can select another BOM from the list. You may want to do this, for example, if the BOM for which the object management was created has been deleted, as shown in the following graphic.
