Diagnosis
Data stream &V3& is assigned todata basis &V1& for datastream type &V2&. However, this data stream is already being used indata basis &V4&. Thus, the assignment of the combination of RFCdestination and InfoCube to the data basis is no longer unique.

System Response
The definition of data basis &V1& cannot be saved with an error.

Procedure
Compare the definition of data basis &V1& with the existing data basisV4. check if you can do without data basis v1 altogether to allowfor a new consolidation area
under data basis &V4&.
If you require both data bases, choose a different data stream for typeV2 by changing either the rfc destination or the infocube.
