有时候需要控制选择画面的parameter来显示和不显示。

这时候我们有两种办法去做控制

1.把这个paramater的text和名字都设置为非显示

  LOOP AT SCREEN INTO DATA(LW_SCREEN).
    IF LW_SCREEN-NAME = '%_P_CLDB_O_%_APP_%-TEXT' OR LW_SCREEN-NAME = 'P_CLDB_O'.
      LW_SCREEN-ACTIVE  = 0.
      LW_SCREEN-INVISIBLE  = 1.
    ENDIF.
    MODIFY SCREEN FROM LW_SCREEN.
  ENDLOOP.

修改之前为

前

修改之后为

后

2.第二种方式是给这些的选择画面的parameter设置modify id

选择屏幕定义代码

SELECTION-SCREEN BEGIN OF BLOCK CLBL04 WITH FRAME TITLE GV_SCR04.
  PARAMETERS:
    P_CLDB_O TYPE TABNAME                      "Table ID
                    MATCHCODE OBJECT DD_TABL
                    OBLIGATORY
                    MEMORY ID DTB.

  PARAMETERS:
     P_CLLANG    TYPE T002-SPRAS DEFAULT SYST-LANGU.

  SELECTION-SCREEN BEGIN OF LINE.
*    SELECTION-SCREEN COMMENT 1(31) GV_TEX01.
    PARAMETERS:
      P_CLNROB TYPE NRIV-OBJECT NO-DISPLAY.    "番号範囲オブジェクト名

*    SELECTION-SCREEN COMMENT 44(23) GV_TEX02.
    PARAMETERS:
      P_CLNRNR TYPE NRIV-NRRANGENR NO-DISPLAY. "範囲間隔区別

  SELECTION-SCREEN END OF LINE.

*SELECTION-SCREEN BEGIN OF BLOCK CLBL05 WITH FRAME TITLE GV_SCR05.
  PARAMETERS:
    P_CLPSDA TYPE  ZAME_PRC_DATE                 "Start date
                     OBLIGATORY
                     DEFAULT SY-DATUM
                     MODIF ID GR5,
    P_CLPSTI TYPE  ZAME_PRC_TIME                 "Start time
                     OBLIGATORY
                     MODIF ID GR5,
    CB_CLEXT AS CHECKBOX DEFAULT 'X'             "extract up to current time
               USER-COMMAND UC1
                    MODIF ID GR5,
    P_CLPEDA TYPE  ZAME_PRC_DATE                 "end date
                     MODIF ID GR1,
    P_CLPETI TYPE  ZAME_PRC_TIME                 "end time
                     MODIF ID GR1,
    P_CLPRDA TYPE  RVARI_VNAM            "execution date id
                     MATCHCODE OBJECT ZAMCMS_TVARVC
                     MODIF ID GR5,
    P_CLPRTI TYPE  RVARI_VNAM            "execution time id
                     MATCHCODE OBJECT ZAMCMS_TVARVC
                     MODIF ID GR5.

*SELECTION-SCREEN END   OF BLOCK CLBL05.
SELECTION-SCREEN END   OF BLOCK CLBL04.

代码如下

  LOOP AT SCREEN INTO DATA(LW_SCREEN).
      IF LW_SCREEN-GROUP1 = 'GR5'.

        LW_SCREEN-ACTIVE  = 0.

        CLEAR:
          P_CLPEDA,
          P_CLPETI.
      ENDIF.
    MODIFY SCREEN FROM LW_SCREEN.
  ENDLOOP.
