上面是完整的程序部分.
其中屏幕中输入有不同的方式，代码部分有相应稍稍的改变
如：1.当前方式
代码：
SELECT-OPTIONS CUST_NO FOR KNA1-KUNNR .
2.Like Table 中要输入的字段方式
PARAMETERS CUST_NO LIKE KNA1-KUNNR.
2.直接输入的方式
SELECTION-SCREEN BEGIN OF BLOCK CHARLY
WITH FRAME TITLE TEXT-001.
SELECTION-SCREEN END OF BLOCK CHARLY.
SELECT-OPTIONS CUST_NO FOR KNA1-KUNNR .
