Diagnosis
Only bills of material for which there are relevant changes aresupposed to be displayed. All changes to a BOM are saved in the changedocument tables under the same objekt ID. For example, changes indifferent alternatives are all saved under the same object ID.

Beispiel
There can be a change document that refers to a change in alternative02. In the meantime, alternative 02 may have been deleted, althoughalternative 01 may still exist under the same object ID. Alternative 02does not exist and can therefore not be displayed. Alternative 01should not be displayed because there is no relevant change.
This and similar constellations are very rare!
