ALV-Grid complex F4

[Former Member]

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

Hi,

While fetching the value for the complex F4,

also provide a check for the initial values of A,

inside tat check, write a piece of code to inform the system what it has to do when the parameter A is empty.

Hope this can solve the problem.

Reward if helpful.

Hi Sharin,

It's standard F4-help, so I don't want to change it. The best decision would be to force ALV not to pass the "A value = space" when the A is emty. I wonder if it's possible.

Thanks.
