hi,

if RG is the reference variable for ur grid then use this method in PAI.

if rg is not initial.

call method rg->check_changed_data.

endif.

this will reflect the changes in the grid into the internal table passed in set_table_for_first_display as it_outtab[].

You have to call method rg->check_changed_data( ) at PAI of your screen. This will trigger event DATA_CHANGED if data of the editable ALV have been changed.

Hi,

to get f4 help for date fields the fields which u have defined in fieldcatalog ,they should refer to the fields of type dats(in database table).

then f4 help automatically comes.

otherwise if u want ur owen f4 help .

then declare a method for the event of handle on f4.

refer to class cl_gui_alv_grid for this event and all the methods ucan use for alv grid.

take this as a sample code i have deleted many lines from this.

there may be many syntax errors in this.

just follow the code for itab_grid[] "table for alv grid.

and rg and rc.

u will definetly get an idea now.
