SAP Message UGMD506 - Node &1 has an ambiguous sequence of subnodes

Diagnosis
When reading the hierarchy structure from remote storage (BW or ERP) thefollowing error occurs:
Node &v1& appears repeatedly, and has an irregular sequence to itssubnodes.
The following found locations are problematic: hierarchies &v2&, &v3&,hierarchy version &v4&.

System Response
In the application, only a standard node structure for all hierarchiesis supported. Consequently, in this instance only the sequence of thesubnodes according to the first found location is transferred.
The display of the hierarchy in the application does not thereforecorrespond to what is expected.

Procedure
Standardize the definition of the hierarchies concerned so that the samenodes within the same validity (version, time) always occur with thesame subnodes in the same sequence in all places.
