The Engineering Change Management (ECM) is used to track and control all the changes with reference to Material master, BOM, Work Center & Routing.
The first step you need to do is to create a Change master thru CC01 T-code. The system will give you one change number. Using this number you can change all the masters record. By default, you need to activate the change number, thru ABAP program, you need to activate this field as a mandatory. Through authorisation we can control the access.
