BDC

问题：

遇到的问题：
1.源字段是一个数值类型，目标字段是一个字符类型，赋值后，从调试中看到字符类型字段里始终为空，百思不得其解。后来我想到，由于字符类型字段长度过长（255），而数值类型赋值到字符类型时默认使用了右对齐，造成实际内容在字符串的右端，从调试器中看不到，赋值到屏幕上也被截断了。
这个问题跟上面一样可以用两种方法解决：
1）target = source.
CONDENSE target. "去出多余空格,保留一个
2）WRITE source TO target LEFT-JUSTIFIED. "左移
DATA: source TYPE p DECIMALS 5 VALUE '20.10392'.
DATA: target TYPE char50.
target = source.
WRITE source TO target LEFT-JUSTIFIED.

2.录屏后会出现同一个字段对应不同的东西，比如 NEWKO 这里我既表示资产号，又表示供应商号。
前面FUNCTION里的输入参数你就要定义2个了，然后再付给NEWKO。

3.转换数据
有的客户系统屏幕用的是欧洲的金额的显示，像10.000,00
录屏时，给的金额显示10000.00,这里就需要转换数据才能完成录屏。
DATA LV_WRBTR(10) TYPE C.
** 转换数据
DATA:
STRING1(1) TYPE C VALUE '.',
STRING2(1) TYPE C VALUE ','.
LV_WRBTR = I_WRBTR.
CONDENSE LV_WRBTR.
REPLACE STRING1 WITH STRING2 INTO LV_WRBTR.
