SET PF-STATUS 'LINE_NUMBER'.

DO 50 TIMES.

Usually the read & Case will be used Combinedly in th ALV drilldown by user command ...

please see the LOGIC of it .

FORM USER_COMMAND.
  PERFORM SET_SCROLL_LINE.
  CASE SY-UCOMM.
    WHEN 'ENTE'.
      READ TABLE IT_DATA WITH KEY WERKS = IT_DATA-WERKS
                                  MATNR = IT_DATA-MATNR.
      IF SYST-SUBRC = 0.
        CASE G_FIELD.
          WHEN 'IT_DATA-VALUE1'.
            IF IT_DATA-VALUE1 <> SPACE.
               SUBMIT (IT_DATA-VALUE1) VIA SELECTION-SCREEN AND RETURN.
            ELSE.
               IT_DATA-VALUE1 = 'Enter 1 Press'(001).
            ENDIF.
          WHEN 'IT_DATA-VALUE2'.
            IT_DATA-VALUE2 = 'Enter 2 Press'(001).
        ENDCASE.
        MODIFY IT_DATA INDEX SYST-TABIX.
      ENDIF.
      PERFORM WRITE_REPORT.
      PERFORM POSITION_LIST.
      CASE G_FIELD.
        WHEN 'IT_DATA-EXP'.
          ADD 1 TO PAGE-CURSLINE.
          SET CURSOR FIELD 'IT_DATA-VALUE1' LINE PAGE-CURSLINE.
        WHEN 'IT_DATA-VALUE1'.
          SET CURSOR FIELD 'IT_DATA-VALUE1' LINE PAGE-CURSLINE.
        WHEN 'IT_DATA-VALUE2'.
          SET CURSOR FIELD 'IT_DATA-VALUE2' LINE PAGE-CURSLINE.
      ENDCASE.
    WHEN 'EXPA'.
      PERFORM SET_EXPAND USING '-'.
      PERFORM WRITE_REPORT.
    WHEN 'COLA'.
      PERFORM SET_EXPAND USING '+'.
      PERFORM WRITE_REPORT.

then another example is :



select ebeln ebelp statu aedat matnr menge meins netpr peinh
 up to 10 rows
  from ekpo
  into corresponding fields of table it_ekko.


FORM user_command USING r_ucomm LIKE sy-ucomm
                  rs_selfield TYPE slis_selfield.

* Check function code
  CASE r_ucomm.
    WHEN '&IC1'.
*   Check field clicked on within ALVgrid report
    IF rs_selfield-fieldname = 'EBELN'.
*     Read data table, using index of row user clicked on
      READ TABLE it_ekko INTO wa_ekko INDEX rs_selfield-tabindex.
*     Set parameter ID for transaction screen field
      SET PARAMETER ID 'BES' FIELD wa_ekko-ebeln.
*     Sxecute transaction ME23N, and skip initial data entry screen
      CALL TRANSACTION 'ME23N' AND SKIP FIRST SCREEN.
    ENDIF.

    WHEN '&DATA_SAVE'.  "user presses SAVE
    loop at it_ekko into wa_ekko.
      if wa_ekko-sel EQ 'X'.
*       Process records that have been selected
      endif.
    endloop.
  ENDCASE.
ENDFORM.
