Hiding/Remove a coloumn in ALV Rep

Hi,

I have developed an ALV report using classes.

Output internal table is dynamically created using method

cl_alv_table_create=>create_dynamic_table and its perfectly working fine.

Now i have to hide/remove the coloumns which doesnt have any values. I am aware of NO_OUT in fieldcatalog, but how can i check whether the coloumn has value or not as my table is being dynamically build.

I cannot use loop at where field <> space as i cant specify the field dynamically in the where clause.

Any hint is really appreciated.

Thanks.
