Hi Gagan
Depen on when you want to read data from list.
You should read data in a module of PAI, but if you want to read only line which are displayed, you should put this module between LOOP/ENDLOOP of tablecontrol, if you want to read whole list you should put this module out of LOOP/ENDLOOP....
and also depen on how you've built the fields of table control.
IF you have called them as the fields of your internal table:
PROCESS PBO.
LOOP AT ITAB WITH CONTROL T_CTRL CURSOR T_CTRL-CURRENT_LINE.
ENDLOOP.
PROCESS PAI.
LOOP AT ITAB.
  MODIFY_ITAB.
ENDLOOP.
MODULE MODIFY_ITAB.
As the output fields of table control are called the
internal table, its headerline is automatically filled:
  MODIFY ITAB INDEX T_CTRL-CURRENT_LINE.
Remenber: here you can see only records which are
displayed
ENDMODULE.
IF the names are different:
PROCESS PBO.
LOOP AT ITAB WITH CONTROL T_CTRL
                             CURSOR T_CTRL-CURRENT_LINE.
  MODULE DISPLAY_RECORD.
ENDLOOP.
PROCESS PAI.
LOOP AT ITAB.
  MODULE MODIFY_ITAB.
ENDLOOP.
MODULE DISPLAY_RECORD.
FIELD_TAB_CTRL1 = ITAB-FIELD1.
FIELD_TAB_CTRL2 = ITAB-FIELD2.
FIELD_TAB_CTRL3 = ITAB-FIELD3.
ENDMODULE.
MODULE MODIFY_ITAB.
  ITAB-FIELD1 = FIELD_TAB_CTRL1.
  ITAB-FIELD2 = FIELD_TAB_CTRL2.
  ITAB-FIELD3 = FIELD_TAB_CTRL3.
  MODIFY ITAB INDEX T_CTRL-CURRENT_LINE.
Remenber: here you can see only records which are
displayed
ENDMODULE.
Now if you want to read whole list:
PROCESS PAI.
LOOP AT ITAB.
  MODULE MODIFY_ITAB.
ENDLOOP.
MODULE LOOP_TABLE.
MODULE LOOP_TABLE.
LOOP AT ITAB.
ENDLOOP.
ENDMODULE.
But you can use USER_COMMAND module instead of LOOP_TABLE module... depend on how you prefer to do that
