Very hard problem I think but we have to solve it.
In Query Selection-Screen I want to show default values which came out of a customer-exit at i_step = 1. This works.
Then I want to change the values manually in the Selection-Screen. This changed values shall be processed for the query. But I additionally want to process this values with further ABAP-coding. This doesn't work.
The problem is that to show a default value, I have to create a variable which is customer-exit AND ready for input. But then this variable is not going to execute i_step = 2 where I could do my ABAP processing.
One solution we tried is to take two variables, one customer-exit , ready for input, another as customer-exit NOT ready to input. We then read the value from the first. This works fine but only for single value selections. Not for selection-options.
Simply you can say:
->show value in selection -> change value manually -> process value in programm -> select data in BW.
Thats what I want.
Does someone can help me for this problem?
