Hi guys.
I have ALV-Grid in which fieldcatalog is created based on DDIC-Structure, let's name it 'STRUC'.
There are 2 fields A and B. In 'STRUC' a complex F4 is seted for these fields: A and B are imported parameters for F4 and B is exported parameter. So everything is good, this F4 is called for fields automatically, and it picks up the values from A and B but.....when field A is empty, then F4 get the space-value as value of A, I mean = ' ', and therefore the initial list of values in F4 is emty.
Does anybody know the way, how I can solve it without using F4-event of Grid and colling the F4 manually?
Thank you
