Diagnosis
From the definition in your data basis it follows that &v2& is used as anode characteristic in hierarchies of characteristic &v1&. This link isin most cases dependent on the assignment of certain roles.
However, the definition of characteristic &v1& in the assigned remotesystem does not corresond to this. Consequently correctsynchronization of the hierarchies for &v1& is not possible.

System Response
You are not able to save the data basis.

Procedure
Either enter field &v2& as an external characteristic in hierarchies inthe definition of field &v1&, or else assign other roles tocharacteristics &v1& or &v2&, so that they are independent of each otherwith regard to hierarchy maintenance.
