SAP S/4HANA銷售訂單建立時，會自動觸發生産訂單的建立

這個自動觸發的過程是怎麼實作的？

使用下面的代碼建立一個銷售訂單：

     ls_headerx        TYPE bapisdhd1x,

用事務碼SAT分析，發現總共建立消耗的時間為3.98秒，

其中1.84秒花費在EIGENFERTIGUNG_BEARBEITEN這個subroutine上。

用一下Google Translate：

發現EIGENFERTIGUNG的含義就和生産有關：own production

BEARBEITEN的意思是TO eidt：

看這個函數CO_61_ORDER_EDIT:

這個函數的描述資訊指向了它是用來做生産用的：

這個函數所在的包也透露了它的作用，是負責生産相關實作的：
