Diagnosis
Too many characteristics are assigned to the given dimension.
For a "normal" InfoCube, the database table to be created for adimension may contain a maximum of 249 fields. This means that no morethan 248 characteristics may be assigned.
However, if the property "DIMIDs One-to-One" is set, a unique index onthe characteristics of the dimension is created. In this case eachdimension may not contain more than 16 characteristics.

Procedure
Assign individual characteristics to another dimension or to a newdimension so that the above limit is not exceeded.
