然后我们需要定义输出界面。把我们查询到的数据输出时要有一个输出的格式， 这样大家看起来才会方便。代码如下：
TOP-OF-PAGE .
WRITE: /'采购凭证号',22 '物料号码',
47 '采购订单数量',77 '收到货物数量',
95 '完成标志'.
ULINE AT /1(130).
END-OF-PAGE .
START-OF-SELECTION.
WRITE: /'采购凭证号',22 '物料号码',
47 '采购订单数量',77 '收到货物数量',
95 '完成标志'.
ULINE AT /1(130).
END-OF-PAGE .
START-OF-SELECTION.
最后就是把我们查到的数据输出了。其实我举的这个程序到这一步时穿插了一些查询，所以比较长。代码如下：
IF R1 = 'X'.
LOOP AT ITAB.
SELECT S~MATNR S~MENGE P~WEMNG S~EBELN
INTO (MATNR, MENGE, WEMNG, EBELN)
FROM EKPO AS S INNER JOIN EKET AS P
ON S~EBELP = P~EBELP AND S~EBELN = P~EBELN
WHERE S~EBELN = ITAB-EBELN.
IF ITAB-MENGE > ITAB-WEMNG.
WRITE: /2 EBELN,23 MATNR,41 MENGE,
71 WEMNG,97 '否'.
ULINE AT /1(130).
CLEAR: EBELN,MATNR,MENGE,WEMNG.
ENDIF.
ENDSELECT.
ENDLOOP.
ELSEIF R2 = 'X'.
LOOP AT ITAB.
SELECT S~MATNR S~MENGE P~WEMNG S~EBELN
INTO (MATNR, MENGE, WEMNG, EBELN)

ULINE AT /1(130).

ENDIF.
ENDSELECT.
ENDLOOP.
ENDIF.
LOOP AT ITAB.
IF R3 = 'X' AND ITAB-MENGE <= ITAB-WEMNG.
SELECT S~MATNR S~MENGE P~WEMNG S~EBELN

这时程序就结束了。其实举这个例子是想让大家知道ABAP开发报表的一个常规流程，并不是讲什么技巧之类的，希望能对初学者有点用。抛砖引玉！
