用CA61,输入物料的Routing所对应的task list代码,可以呼出这个routing在时间段落内的old value vs. new value。
If you create or change a bill of material with reference to a change number, there is a history requirement if you wish to change the BOM later on.
You need a special authorization to change the BOM later on without reference to a change number.
Good luck!
