REPORT ZTEST904 .

*定义需要使用的表
***********************************************
TABLES: MSEG,
        MARA,
        MKPF.

*定义一个内部表(带表头)
***********************************************
DATA:   BEGIN OF ITAB OCCURS 0,
            A LIKE MSEG-MBLNR,
            B LIKE MSEG-ZEILE,
        END   OF ITAB.


* 插入一些使用的数据。
***********************************************
DO 30 TIMES.
  ITAB-A = '测试数据'.
  ITAB-B = SY-INDEX.
  APPEND ITAB.
ENDDO.

* 显示画面数据，显示上面的打印按钮。用户点击打印
* 然后调用打印的SCRIPT。显示答应的数据。
