Hi,

for giving default F4help which is available then you can make use of REF_FIELD , REF_TABLE this will enable F4 help.

and second you want to save the contents to DB only few or Full data.

and are you editing any thing in the grid?

i think that is the reason you are asking to save is it so?

if so then you can use help of pf-status and user_command , then while pressing the save button you can modify the DB in user_command form.

I need to give my own F4 help depending on contents of one of the cell in ALV grid

and secondly yaa we are allowing user to make changes to certain fields and then we want to save the contents to db table

[former_member188685]

Hi,

Not sure in normal ALV, but it can be done in OO ALV with help of events.

seocnd one is simple , when user clicks on SAVE button you need to modify the DB.

We are using object oriented ALV

as all these things can not be done in simple ALV
