Hello Jürgen,
thank you for your help. But this is exactly what I have done.
For testing, I set an external breakpoint at the beginning of the method and I can see that this method is not executed when I start the query (also after selection screen). The input table appears and all cells are ready for input.
When I change some data and start a planning function, than I come to the breakpoint.
Regards
Jürgen
