How To Fix BRAIN431 - InfoObject &1 must be selected uniquely in all cells

BRAIN431 - Overview

• Message type: E = Error

• Message class: BRAIN -

• Message number: 431

• Message text: InfoObject &1 must be selected uniquely in all cells

What causes this issue?

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 is not
the case for selection element &V3& or the fixed filter.
The change to the metadata was probably made after the query was
defined.(You can access this setting in the InfoObject maintenance on
the <ZK>Business Explorer</> tab page, under the group heading <ZK>
General Settings</> -><ZK> Selection</> ; or in InfoCube maintenance,
via <ZK>Extras</> -> <ZK>Structure-specific InfoObject Properties</> ->
<ZK>Selection</>.)

System Response

The query cannot be generated nor executed.

How to fix this error?

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