Pretty hint ...
I moved to-dep-pk from 'source' to 'target' of the relation ... it worked
A little strage because the join-fields were filled in on both sides
It is a typical optional Information that ist attached by the 1:1 relation
so to-dep-pk would be right on both sides of the relation.
Thanx ...
