最近偶然写个选择屏幕的帮助，太久不写这些了，忘了很多，然后网上查了一下。

这个demo是返回多值的。

效果：

就是选择工厂的时候把剩下的几个字段自动带过去。

另外，不允许手工输入，防止仨字段不配套嘛。

代码很简单：

TYPES: SHLP_DESCR_T TYPE SHLP_DESCR .
DATA: BEGIN OF ITAB OCCURS 0 ,
        WERKS LIKE  T001W-WERKS,
        NAME1 LIKE  T001W-NAME1,
        BWKEY LIKE T001W-BWKEY,
      END OF ITAB.
DATA: RETURN_TAB TYPE DDSHRETVAL OCCURS 0 .
PARAMETERS: P_WERKS LIKE T001W-WERKS,
            P_NAME1 LIKE T001W-NAME1,
            P_BWKEY LIKE T001W-BWKEY.


INITIALIZATION.
  SELECT * FROM T001W INTO CORRESPONDING FIELDS OF TABLE ITAB[]
    WHERE SPRAS = '1'.


AT SELECTION-SCREEN OUTPUT .
  PERFORM FRM_SCREEN.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_WERKS .
  PERFORM F4.

  APPEND INTERFACE TO SHLP-INTERFACE.


  INTERFACE-SHLPFIELD+4(1) = '3'.
  INTERFACE-VALFIELD = 'P_BWKEY'.
  APPEND INTERFACE TO SHLP-INTERFACE.
ENDFORM.                    "bo_callback_form

FORM FRM_SCREEN .
  LOOP AT SCREEN.
    SCREEN-INPUT = 0.
    MODIFY SCREEN.
  ENDLOOP.

仅仅是个简单demo，仅供参考，项目上自己看着写吧。

我网上查资料的时候是参考的老白的文章
