• Message number: 505

• Message text: Node &1 has an ambiguous substructure - see long text

What causes this issue?

When reading the hierarchy structure from the remote storage (BW or ERP)
the system encountered the following error:
Node &v1& appears repeatedly and has <ZH>variously assigned subnodes
</>.
The following found locations are problematic: hierarchies &v2&, &v3&,
hierarchy version &v4&

System Response

When reading the hierarchy, there is overlapping of the subnodes for all
found locations.
In the result, <ZH>all</>subnodes found are uniformly assigned to node
&v1&.
The display of the hierarchy in the application differs from what is
expected.

How to fix this error?

You can either standardize the hierarchies concerned, or limit the
reading to a single hierarchy.
