SAP Message BRAIN431 - InfoObject &1 must be selected uniquely in all cells

Diagnosis
InfoObject &V1& (&V2&) has the setting in the metadata (COB_PRO-CHSEL= 2) that a unique value has to be determined in every cell. This isnot the case for selection element &V3& or the fixed filter.
The change to the metadata was probably made after the query wasdefined.(You can access this setting in the InfoObject maintenance onthe Business Explorer tab page, under the group heading General Settings -> Selection ; or in InfoCube maintenance,via Extras -> Structure-specific InfoObject Properties ->Selection.)

System Response
The query cannot be generated nor executed.

Procedure
Characteristic &V1& must set to a unique value in the fixed filter orin each selection element of the structure/ in all exception cells.You can do this using a parameter variable with mandatory entry. Youcan also use characteristic &V1& as a free characteristic.
Alternatively, you can change the settings for characteristic &V1& inthe InfoObject maintenance, or the settings for this InfoCube in theInfoCube maintenance.
