Diagnosis
You try to link a master characteristic and a class characteristic thatis a standard characteristic for batches. This is not allowed, sincethe batch valuation for these characteristics does not take place in aquality inspection.

Example
The class characteristic LOBM_QSCORE (characteristc short text:"Quality score") is automatically valuated with the quality score ofthe usage decision. It cannot, therefore, be supplied with values froman inspection characteristic from a quality inspection.
For this reason, the link is not allowed.
