Answer 1

this will be your's main program
*& Report  ZEMP
REPORT  ZEMP.
TABLES: ZEMP." Z TABLE
CONTROLS: TAB_CONTROL TYPE TABLEVIEW USING SCREEN 1000.
DATA: IT LIKE ZEMP OCCURS 0 WITH HEADER LINE.
SELECT * FROM ZEMP INTO CORRESPONDING FIELDS OF TABLE IT.
CALL SCREEN 1000.
*&      Module  STATUS_1000  OUTPUT
      text
MODULE STATUS_1000 OUTPUT.
SET PF-STATUS 'xxxxxxxx'.
SET TITLEBAR 'xxx'.
ENDMODULE.                 " STATUS_1000  OUTPUT
*&      Module  USER_COMMAND_1000  INPUT
      text
MODULE USER_COMMAND_1000 INPUT.
  IF SY-UCOMM = 'BACK'.
    LEAVE PROGRAM.
  endif.
ENDMODULE.                 " USER_COMMAND_1000  INPUT
*&      Module  MODIFY  INPUT
      text
MODULE MODIFY INPUT.
  MODIFY IT INDEX TAB_CONTROL-CURRENT_LINE.
  MODIFY ZEMP FROM IT.
ENDMODULE.                 " MODIFY  INPUT
and this should be your flow logic
PROCESS BEFORE OUTPUT.
MODULE STATUS_1000.
LOOP AT IT WITH CONTROL TAB_CONTROL.
ENDLOOP.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_1000.
LOOP AT IT.
MODULE MODIFY.
ENDLOOP.
