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。
