Invalid use of DP BOM auxiliary characteristics

What causes this issue?

In the definition of the planning area, you have defined at least one
DP BOM key figure pair (semantic 40X/50X) with and without
corresponding auxiliary key figure (semantic 60X). However, this is not
allowed. A corresponding auxiliary key figure with semantic 60X must be
defined either for all key figure pairs or for none.

System Response

The action has been terminated due to detected inconsistencies.

How to fix this error?

If you wish to use auxiliary key figures to improve calculation
accuracy (semantic 60X), add a suitable auxiliary key figure (semantic
60X) to all DP BOM key figure pairs (semantic 40X/50X).
If you do not wish to use auxiliary key figures, remove all key figures
with semantic 60X from the planning area.
