ABAP DILOG实现SELECT-OPTION 功能

DILOG中没有SELECT-OPTION控件，所以无法直接去定义，这时候可以通过子屏幕引用去实现，首先在代码中定义一个子屏幕，代码如下：

SELECTION-SCREEN BEGIN OF SCREEN 1001 AS SUBSCREEN.
SELECT-OPTIONS s_pernr FOR pa0001-pernr NO INTERVALS.
SELECTION-SCREEN END OF SCREEN 1001.

在屏幕逻辑流中调用创建的子屏幕：

PROCESS BEFORE OUTPUT.
  MODULE status_0100.
  CALL SUBSCREEN sub INCLUDING repid '1001'.
PROCESS AFTER INPUT.
 CALL SUBSCREEN sub.
