SAP 选择屏幕常用工具（字段分组、字段分配搜索帮助等）

1. 对“选择屏幕字段”进行分组

SELECTION-SCREEN BEGIN OF BLOCK bk2 WITH FRAME TITLE TEXT-002.
SELECT-OPTIONS: s_kschl FOR rv13a-kschl MODIF ID bk2.
SELECT-OPTIONS: s_vtweg FOR komg-vtweg MODIF ID bk2.
SELECT-OPTIONS: s_matnr FOR komg-matnr MODIF ID bk2.
PARAMETERS: p_datab TYPE rv13a-datab OBLIGATORY MODIF ID bk2.
SELECTION-SCREEN END OF BLOCK bk2 .

通过组ID进行相关操作

  CASE 'X'.
    WHEN p_1.
      LOOP AT SCREEN.
        IF screen-group1 = 'BK2'.
          screen-active = 0.
          MODIFY SCREEN.
        ENDIF.
      ENDLOOP.
    WHEN p_2.
      LOOP AT SCREEN.
        IF screen-group1 = 'BK1'.
          screen-active = 0.
          MODIFY SCREEN.
        ENDIF.
      ENDLOOP.
    WHEN OTHERS.
  ENDCASE.

2. 分配搜索帮助到选择屏幕字段

SELECT-OPTIONS: S_VKBUR  FOR VBAK-VKBUR.
SELECT-OPTIONS: S_VKGRP  FOR VBAK-VKGRP.
SELECT-OPTIONS: S_VKGRP1 FOR VBAK-ZZVKGRP1 MATCHCODE OBJECT ZSD_ZZVKGRP1.
SELECT-OPTIONS: S_VKGRP2 FOR VBAK-ZZVKGRP2 MATCHCODE OBJECT ZSD_ZZVKGRP2.
