Diagnosis
All version combinations that refer to the same version combination inCustomizing Special Versions -> Storage of Additional Financial Data
, must have assigned the same special validity version in inCustomizing Special Versions -> Assign to Combinations for allcharacteristics. (Otherwise you would have restricted read or writeaccess in some version combinations.)
However, this is not the case for characteristic &V1& and versioncombinations &V2& and &V3&.

Procedure
In Customizing Special Versions -> Assign to Combinations, changethe special validity version of characteristic &V1& in versioncombinations &V2& or &V3& so that it has the same special validityversion in both version combinations.
Alternatively, you can assign different special versions to versioncombinations &V2& and &V3& for special version type &V4& in CustomizingSpecial Versions -> Assign to Combinations. Then you must adjustthe Customizing Special Versions -> Storage of Additional FinancialData appropriately.
