Hi
U have 2 ways:
A) By the statament GET CURSOR: insert a module in PAI into the loop of the table control in order to get the line where the cursor is: If the user press a button the cursor shoud be there.
PROCESS PAI.
   LOOP AT .....
      MODULE GET_CURSOR.
   ENDLOOP.
   MODULE USER_COMMAND.
MODULE GET_CURSOR.
  GET CURSOR LINE VN_LINE.
ENDMODULE.
MODULE USER_COMMAND.
    CASE OK_CODE.
      WHEN <PUSH BUTTON>.
* It needs to know the number of the record of the internal table assigned to the line of table
* control with the push button pressed.
* VN_LINE has the value of the line of table control so:
         VN_TABIX = <TABLE CONTROL>-TOP_LINE + VN_LINE - 1.
         READ TABLE ITAB INDEX VN_TABIX.
* Do something......
ENDMODULE.
A) U can assing the sign % to the ok-code of the pushbutton, after pressing it the system'll replace it with the value of the pressed line.
MODULE USER_COMMAND.
    CASE OK_CODE.
* The ok-code for the pushbutton is ABCD%
      WHEN OTHERS.
          IF OK_CODE(4) = 'ABCD'.
            VN_LINES = OK_CODE+4.
* It needs to know the number of the record of the internal table assigned to the line of table
* control with the push button pressed.
* VN_LINE has the value of the line of table control so:
             VN_TABIX = <TABLE CONTROL>-TOP_LINE + VN_LINE - 1.
            READ TABLE ITAB INDEX VN_TABIX.
* Do something......
           ENDIF.
ENDMODULE.
