• Message number: 013

• Message text: Key field &1 is not from table &2, as the others

What causes this issue?

The search engine needs all key fields to come from the same data base
table; including the client field. This is not the case here. The first
key field are from data base table &V2&; key field &V1& is from another
table.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Remove element &V1& from the key definition in annotation
@ObjectModel.semanticKey. Check whether the field- if needed - can be
taken alternatively from table &V1&, as the other key field(s).
Mind that this is independently of how the view stack looks like - it is
the actual data base table which is decisive.
