我们通过调用内置函数POPUP_GET_VALUES来实现弹框数据某些对应的数据内容. 具体参数以及语法如下.

  CALL FUNCTION 'POPUP_GET_VALUES'
      EXPORTING
*       NO_VALUE_CHECK  = ' '
        popup_title     = '物料商品选择'
*       START_COLUMN    = '5'
*       START_ROW       = '5'
      IMPORTING
        returncode      = lv_rtn_cd
      TABLES
        fields          = it_value
      EXCEPTIONS
        error_in_fields = 1
        OTHERS          = 2.
    IF sy-subrc = 0.
      LV_STGRD =  it_value[ 1 ]-value   .
      LV_BUDAT =  it_value[ 2 ]-value   .
      LV_MONAT =  it_value[ 3 ]-value   .

      ENDIF .

popup_title ：弹窗的标题

fields 表中存储要和用户交互的字段，

每个字段有三个参数分别是tabname：参考表；fieldname：字段名称；value：默认值。

要求字段名称必须是参考表中的数据，会自动带出搜索帮助。

START_COLUMN和START_ROW 是弹窗位置

实际案例

*数据准备
  DATA LV_STGRD TYPE RF05R-STGRD .
  DATA LV_BUDAT TYPE RF05R-BUDAT .
  DATA LV_MONAT TYPE RF05R-MONAT .
  DATA: it_value  TYPE TABLE OF sval,
        wa_value  TYPE sval,
        lv_rtn_cd.
*操作数据
    wa_value-tabname = 'BKPF'.
    wa_value-fieldname = 'STGRD'.
    wa_value-value = '01'.
    APPEND wa_value TO it_value.
    wa_value-tabname = 'BKPF  '.
    wa_value-fieldname = 'BUDAT'.
    wa_value-value = sy-datum   .
    APPEND wa_value TO it_value.
    wa_value-tabname = 'BKPF'.
    wa_value-fieldname = 'MONAT'.
    wa_value-value = sy-datum+4(2).
    APPEND wa_value TO it_value.
*调用函数

    CALL FUNCTION 'POPUP_GET_VALUES'
      EXPORTING
*       NO_VALUE_CHECK  = ' '
        popup_title     = '冲销数据'
*       START_COLUMN    = '5'
*       START_ROW       = '5'
      IMPORTING
        returncode      = lv_rtn_cd
      TABLES
        fields          = it_value
      EXCEPTIONS
        error_in_fields = 1
        OTHERS          = 2.
    IF sy-subrc = 0.
      LV_STGRD =  it_value[ 1 ]-value   .
      LV_BUDAT =  it_value[ 2 ]-value   .
      LV_MONAT =  it_value[ 3 ]-value   .

      ENDIF .


     WRITE : LV_BUDAT .
