Engineering change management is only used to process global object dependencies that can be identified by the name of the dependency.
Local object dependencies are saved in the SAP object which is maintained locally (for example: BOM item).

If you want to use the change number for configuration profiles with object dependencies, you should define the settings for object types such that object dependencies can be processed with reference to this change number.

You can process the contents of a variant table with reference to a change number. You cannot process the table structure with reference to a change number.
