項目中，經常用到，點擊按鈕時彈出一個對話框，選擇一些值，然后返回選擇的值，進一步操作，下面是使用彈窗對話框函數POPUP_GET_VALUES返回日期的例子，當然后也可以時其他類型的，定義數據元素時，根據需要定義成相應的類型就行了，效果如下圖：

代碼如下：

??DATA:?it_value?TYPE?TABLE?OF?sval,

??????? wa_value?TYPE?sval,

????????lv_rtn_cd.

??CLEAR:it_value,wa_value,lv_rtn_cd.
??IF?lv_cmd?=?'1'?OR?lv_cmd?=?'2'.
????wa_value-tabname?=?'ZMMDATE'.
????wa_value-fieldname?=?'BDATE'.
????wa_value-value?=?sy-datum.
????APPEND?wa_value?TO?it_value.


????wa_value-tabname?=?'ZMMDATE'.
????wa_value-fieldname?=?'EDATE'.
????wa_value-value?=?sy-datum.
????APPEND?wa_value?TO?it_value.
??ELSE.
????wa_value-tabname?=?'ZMMDATE'.
????wa_value-fieldname?=?'JDATE'.
????wa_value-value?=?sy-datum.
????APPEND?wa_value?TO?it_value.
??ENDIF.


??CALL?FUNCTION?'POPUP_GET_VALUES'
????EXPORTING
??????popup_title?=?'日期選擇'
????IMPORTING
??????returncode??=?lv_rtn_cd
????TABLES
??????fields??????=?it_value.

??DATA:gt_itab?TYPE?TABLE?OF?zputwbsrq_s?WITH?HEADER?LINE.
??DATA:msg?TYPE?TABLE?OF??zbapimessage?WITH?HEADER?LINE.

??DATA:gt_in?TYPE?TABLE?OF?zputprrq_s?WITH?HEADER?LINE.

??DATA:msg1?TYPE?TABLE?OF?zbapiret?WITH?HEADER?LINE.

??DATA:gt_in2?TYPE?TABLE?OF?zputplrq_s?WITH?HEADER?LINE.

??IF?lv_rtn_cd?IS?INITIAL.
????????READ?TABLE?it_value?INTO?wa_value?WITH?KEY?fieldname?=?'BDATE'.
????????IF?sy-subrc?=?0.
??????????gt_itab-p_day?=?wa_value-value.
??????????gt_itab-b_day?=?wa_value-value.
????????ENDIF.
????ENDIF.
