Diagnosis
All changes in a BOM object are saved in the change document tablesunder the same object ID. For example, changes in differentalternatives are all saved under the same object ID.

Beispiel
If the selected change document only applies for alternative 02, whichhowever has been deleted in the meantime, no change can be displayedunder the selectable or existing alternatives that belong to theselected change document. It is also possible that, for example, a BOMitem was inserted and later deleted.
Such special cases are rare but happen more often depending on how oldthe change document is with regard to the time of selection.
