    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.
