Write to 和 Move to 的区别

WRITE ... TO 把源的格式 附值到目标。

MOVE ... TO 直接把源的值附到目标。

示例：

data: gv_char1(20) type c,
     gv_char2(20) type c,
     dec1(10) type p decimals 2 value '22345.89'.

start-of-selection.
* date *
write:/ 'date variable'.
write sy-datum to gv_char1.
write:/ 'write to', gv_char1.
move sy-datum to gv_char2.
write:/ 'move to', gv_char2.
skip 1.
* decimal *
write:/ 'decimal variable'.
write dec1 to gv_char1.
write:/ 'write to', gv_char1.
move dec1 to gv_char2.
write:/'move to', gv_char2.

结果：

date variable
write to 2008-11-09
move to 20081109

decimal variable
write to 22,345.89
move to   22345.89
