How To Fix BRAIN396 - Reference characteristic &1 is probably not suitable for &2

BRAIN396 - Overview

• Message type: E = Error

• Message class: BRAIN -

• Message number: 396

• Message text: Reference characteristic &1 is probably not suitable for &2

What causes this issue?

In formula or key figure &V4& aggregation &V2& is used with reference
characteristic &V1& . The basic key figure going into &V4& is not a
non-cumulative key figure, however.
The query now uses the finer time characteristic &V3& or a time
characteristic that cannot be derived from&V1& .
Formation of averages will therefore produce confusing results if &V3&
is expanded.

How to fix this error?

Check the query definition, in particular &V4&
