Best Practice for AiF Queries 2

[ideveloper]

Thank you for your replies

Sergikrus: I am familar with this method. It is simple to use. But I was hoping, that there is a possibility to inherit the queries and throw away tables which are not needed. If I duplicate a Query and create a service with the AiF-Wizard I get new Classes according to the new Query which have the same functionality like the Classes from the "Parent"-Query.
It is not only the Query which is duplicated, there are Classes too.
