A basic SAP Engineering Change Management Setup

To activate "Engineering Change Management", what are the settings that are needed? 

Engineering Change Management is used to track and control all the changes with reference to Material master, BOM, Work Center & Routing. 

This are the basic IMG settings in order to used the engineering change management features.

 x
refers to a tick.

First setup the control data in OS54.

Revision sections

Higher revision level            x

Object Management Record sections

Fields :-

Overide value/assignment date sections

Fields :-

Setting the Revision level active is to activate the engineering change management 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.

Fourth, define modification parameters for the BOM in OS27.

Fields :-

The rest of the fields are blank.
If the History Requirement is tick, every time during creation of the BOM, SAP willprompt your for an ECN number as is compulsory.
