SAP Engineering Change Management is a central logistics function that can be used to change various aspects of production basic data (for example, BOMs, task lists, materials, and documents) with history (with date effectively) or depending on specific conditions (with parameter effectively).
The following is a sample basic SAP Engineering Change Management Setup.
These are the basic IMG settings in order to use the Logistics Engineering Change Management features.
The x refers to a tick.
Firstly setup the control data in OS54.
Revision sections

Fields Name :-

Setting the Revision level active is to activate the ECM for material master. If you do not want the engineering change management for materials, remove the tick.
With a tick in "Higher revision level", the new revision level has to be always higher than the old revision.
Secondly, setup the external number range in OS53.
If you use the internal number range, then remove the external number range.
Third, define the status for the change master records in transaction SM30 - V_T419S.

The rest of the fields are blank.
If the History Requirement is tick, every time during creation of the BOM, SAP will prompt you for an ECN number as is compulsory.
Lastly, define fields selection for routing in OP5A.
PP task lists: initial screen -> Change number -> Transaction code -> Tick Req.
Setting the Transaction code fields Required indicate that you have make the ECN number compulsory when changing the routing.
Finally, test it by making changes to the Material Master, BOM and Routing.
