with ALV function call, is it possible to modify the field catalog when processing the event form 'USER_COMMAND'?
Before calling the display, I generate the field catalog. Then I set all unpopulated columns (field is initial in all lines) to 'TECH'. So I see only 'active' columns.
Now, the user can do some interaction which will change the lines values. In event routine for 'USER_COMMAND, I set the selfield-refresh = 'X'.
But now, for some fields, I want to remove the 'TECH' attribute of the field catalog because they get populated.
How to achieve this?
