1 定义命令处理Form
FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
                  RS_SELFIELD TYPE SLIS_SELFIELD.

  DATA: VBELN1 LIKE L_SPETAB-VBELN, VBTYP1 LIKE L_SPETAB-VBTYP.
  RS_SELFIELD-REFRESH = 'X'.     "控制grid产生新屏幕
  CASE R_UCOMM.
    WHEN  'BEAN' OR '&IC1'.  "双击事件
      LOOP AT L_SPETAB WHERE SELK = 'X' .
        VBELN1 = L_SPETAB-VBELN.
        VBTYP1 = L_SPETAB-VBTYP.
        CALL FUNCTION 'RV_CALL_CHANGE_TRANSACTION'
          EXPORTING
            VBELN = VBELN1
            VBTYP = VBTYP1.

        COL = COL_BEARBEITEN.
        FARB-FARB2 = COL.
        L_SPETAB-COL = FARB.
        LF_LAYOUT-INFO_FIELDNAME    = 'L_SPETAB-COL'.   
        MODIFY L_SPETAB.
        CLEAR: VBELN1, VBTYP1.
      ENDLOOP.
      IF SY-SUBRC NE 0.
        READ TABLE L_SPETAB INDEX RS_SELFIELD-TABINDEX.
        IF SY-SUBRC = 0.
          REPLACE '1-' WITH ' ' INTO RS_SELFIELD-SEL_TAB_FIELD.
          CONDENSE RS_SELFIELD-SEL_TAB_FIELD NO-GAPS.
          FELD = RS_SELFIELD-SEL_TAB_FIELD.
          PERFORM SELECT USING RS_SELFIELD-TABINDEX.
          CLEAR FELD.
        ENDIF.
      ENDIF.
      RS_SELFIELD-COL_STABLE = 'X'.
      RS_SELFIELD-ROW_STABLE = 'X'.
  ENDCASE.

ENDFORM.                    "USER_COMMAND

2 定义一个常量包含"USER_COMMAND"
DATA:    L_USER_COMMAND TYPE SLIS_FORMNAME VALUE 'USER_COMMAND'.

3 调用REUSE_ALV_GRID_DISPLAY
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
       EXPORTING

            IT_FIELDCAT              = LF_FIELDCAT[]
*           IT_EXCLUDING             =
*           IT_SPECIAL_GROUPS        = LF_SP_GROUP
*           I_DEFAULT                = 'X'
*           I_SAVE                   = L_SAVE
*           IS_VARIANT               = L_VARIANT
*           IT_EVENTS                = LF_EVENTS[]
*           I_SCREEN_START_COLUMN    = 0
*           I_SCREEN_START_LINE      = 0
*           I_SCREEN_END_COLUMN      = 0
*           I_SCREEN_END_LINE        = 0
*     IMPORTING
*           E_EXIT_CAUSED_BY_CALLER  =
*           ES_EXIT_CAUSED_BY_USER   =
       TABLES
            T_OUTTAB                 = L_SPETAB .
