System Response

The system has to derive the representative key field automatically at
runtime. However, this may lead to unexpected results.

How to fix this error?

We recommend explicitely defining the appropriate key field as a
representative key field by setting the semantics <LS>Representative Key
</> for the corresponding node attribute in the maintenance of the
corresponding model node.
