FI_ITEMS_MASS_CHANGE 批量更新 憑證文本，這個函數本身也是個BDC的程序 ，一行一行的去更改憑證行項目，問題是，LOOP循環批量更新的時候常發生 Item 001得到更改，Item 002 003 卻沒有改， 并給出錯誤說：憑證被鎖。 起原因是原函數是異步更新的，參見原函數中的：

????call?transaction?'FB02'??using????bdcdata
?????????????????????????????mode? ? bdcmode
?????????????????????????????update???'A'
?????????????????????????????messages?into?msgtab.

其中?update???'A'即是 。

在 T-code se80 中 把原函數copy一份出來，修改這里為：

????call?transaction?'FB02'??using????bdcdata
?????????????????????????????mode?????bdcmode
*?????????????????????????????update???'A'
?????????????????????????????update???'S'
?????????????????????????????messages?into?msgtab.

這就是同步更新，但是比較慢點 。
