How To Fix UGMD506 - Node &1 has an ambiguous sequence of subnodes

SAP Error Message - Details

• Message type: E = Error

• Message class: UGMD - FIN Master Data: Messages

• Message number: 506

• Message text: Node &1 has an ambiguous sequence of subnodes

What causes this issue?

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

System Response

In the application, only a standard node structure for all hierarchies
is supported. Consequently, in this instance only the sequence of the
subnodes according to the first found location is transferred.
The display of the hierarchy in the application does not therefore
correspond to what is expected.

How to fix this error?

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