TableControl - determine marked line

Question

Hello,
i have a beginner question:
We show some data in a table control and want to delete the line from database which the user has selected.
Where and how do we have to identify the line to delete?
Thanks for help,

Hi,
The database table should contain a character field of length 1 (say mark) in addition to other fields.
In PAI , you have to loop like this.
PROCESS AFTER INPUT.
*itab is the name of the internal table with header line
  LOOP AT itab.
Marking the row to be deleted by using this field(mark)
    FIELD itab-mark MODULE check.
  ENDLOOP.
  MODULE user_command_9000.
declaration
here zzz_abc is the name of the database table which
should contain mark as one of the field
DATA : itab TYPE STANDARD TABLE OF zzz_abc WITH HEADER LINE.
CONTROLS: t_ctrl TYPE TABLEVIEW USING SCREEN '9000'.
MODULE check INPUT.
  MODIFY itab INDEX t_ctrl-current_line.
ENDMODULE.                 " CHECK  INPUT
MODULE user_command_9000 INPUT.
  DATA :lv_fcode LIKE sy-ucomm,    "Function Code
        lv_answer(1) type c.       "Storing the answer
  lv_fcode = sy-ucomm.
  CASE lv_fcode.
    WHEN 'DELETE'.
Setting the flag to make the table control in editable * mode after deleting the selected line
      flg = 'Y'.
Confirmation of delete
      CALL FUNCTION 'POPUP_TO_CONFIRM'
        EXPORTING
         TITLEBAR       = 'Confirm'
         text_question  = 'Are you sure to delete from database?'
         TEXT_BUTTON_1  = 'Yes'(001)
         TEXT_BUTTON_2  = 'No'(002)
        IMPORTING
         ANSWER         =  lv_answer.
      if lv_answer eq '1'.
Updating the database table from the internal table
        UPDATE zzz_abc FROM TABLE itab.
Deleting the selected row from the internal table
        DELETE itab WHERE mark = 'X'.
Deleting the selected row from the database table
        DELETE FROM itab WHERE mark = 'X'.
        MESSAGE s005 WITH 'Deleted Successfully'.
      ENDIF.
ENDMODULE.                 " USER_COMMAND_9000  INPUT
