How to fix this error?

The data origin of both fields must be the same. The subordinate field
must conform to the superior one.
&EXAMPLES&
The fields "PlanPlant" and "PM PlanGroup" are dependent on one another.
Only certain
maintenance planning groups are to be
found in a particular
planning plant.
The data origin of the subordinate field "PM PlanGroup" therefore has
to be the same as that of the superior field "PlanPlant".
