ABAP如何自定义下拉列表 .

1. 在选择屏幕上添加下拉列表控件, 代码如下：

  PARAMETERS: auart LIKE vapma-auart AS LISTBOX   VISIBLE LENGTH 6 

    DEFAULT ‘ZESC‘ OBLIGATORY.

2. 手工添加下拉列表数据， 代码如下:

  *&---------------------------------------------------------------------*
*&      Form  fill_data_to_auart
*&---------------------------------------------------------------------*
*       to fill data for combo auart.
*----------------------------------------------------------------------*
FORM fill_data_to_auart .
  TYPE-POOLS: vrm . "存放combobox内容的type pool
  DATA: name TYPE vrm_id, " list box的名称
        list TYPE vrm_values, " list box的值
        value LIKE LINE OF list . " list box的结构

  REFRESH list .

  DEFINE fill_list.
    value-key = &1.  "个就是变量P_LIST的值
    value-text = &2. "这个是text
    append value to list.
  END-OF-DEFINITION.

  fill_list ‘ZESC‘ ‘ZESC‘.
  fill_list ‘ZESE‘ ‘ZESE‘.
  fill_list ‘ZEDN‘ ‘ZEDN‘.
  fill_list ‘ZEEN‘ ‘ZEEN‘.
  fill_list ‘ZPBB‘ ‘ZPBB‘.
  fill_list ‘ZPBE‘ ‘ZPBE‘.
  fill_list ‘ZPDN‘ ‘ZPDN‘.
  fill_list ‘ZPEN‘ ‘ZPEN‘.
  fill_list ‘ZOCS‘ ‘ZOCS‘.
  fill_list ‘ZASC‘ ‘ZASC‘.
  fill_list ‘ZASE‘ ‘ZASE‘.
  fill_list ‘ZADN‘ ‘ZADN‘.
  fill_list ‘ZAEN‘ ‘ZAEN‘.

  "---〉调用函数显示listbox里面的值
  CALL FUNCTION ‘VRM_SET_VALUES‘
    EXPORTING
      id     = ‘AUART‘  " PARAMETERS‘s Name
      values = list.
ENDFORM.                    " fill_data_to_auart

 

3. 在 AT SELECTION-SCREEN OUTPUT. 事件中填充数据，代码如下：

    PERFORM fill_data_to_auart.

 

以上代码，ECC6环境下通过。
