Hi,

In the user command of the screen you can put the logic for modifying your internal table from the fields in the table control.

and from that modify the databse table.

Hi Viju,

In PAI do something like this

LOOP AT itab.
    MODULE mod_table_control.
ENDLOOP.
MODULE user_command_0100.

at module mod_table_control put this

MODULE mod_table_control INPUT.
  MODIFY itab FROM demo_conn INDEX flights-current_line.
  if sy-subrc ne 0.
       insert itab.
  endif.
ENDMODULE.

for saving you can create at custom gui status with a save button, and at MODULE user_command_0100 save the data.
