ALV: F4 help for a column wanted, but without any check
I have an ALV and I use a DDIC structure for the field catalog. My requirement is that for all columns in ALV, the F4 should appear normally (using the DDIC information), but I do not want an automatic check for the value entered by user.
So .e.g. if in F4, possible values are 1, 2, 3 then the ALV throws an error if user leaves the field blank (because blank was not a possible value for the domain of the field). How, can I by-pass this automatic check by ALV (while still keeping the F4 help)?
