fist of all thank you very much for your support. My last issue has been solved very quick.
Now I have a new problem regarding inheritance between two packages.
I have two tables which are located in different packages.
Now I want in Model A to create an inheritance tree where Table 2 inherits from Table1. This is not possible by default. The only way I have found out is to create an extra package and move the tables there and use the inheritance as a shortcut in model A.
Is this possible without this workaround?
Thank you very much. I hope the explanation is understandable.
