Engineering Change Management and Revision Levels

Hi,

I have earlier read a thread by Vivek and Janev on a forum question on Revision levels. However, I am still confused by it. Do we need to use Revision Level together with Engineering Change Management (ECM) ? I understand that one allows to you to keep track of how many revisions you have made (Revision Level), while ECM allows you to know why you made the change and when it is valid. Is there further details on why they are used?

Thanks so much.

Rgds,

    To cover your question on why its used, there are a couple of reasons:

    1. Group associated changes. I.e. if there is an incident on site, you can use a single change number to change a number of documents (procedure, drawing, MSDS etc) and group the change with the change master so that anyone viewing the document can see why the change happened, and what other objects were effected by the change (you can obviously include other SAP objects, not just documents). The relationship of these associated changes can be viewed in CC04 (Product Structure Browser)

    2. To manage change. I.e. forcing a user to request a change number from a superior before commencing with a change will ensure that documents aren't random created in the system, particularly in a drawing environment where you don't want draughtsman randomly creating new versions of drawings without the required permissions.

    3. Logging change. I.e. why change happens using the reason in the change master

    There are various other reasons, but those are the primary ones.

      Hi Pavana,

      I have a small doubt in your explanation. Which object i should add if i want to change the Material master alone not BoM. If i see the Objects list i found all the objects, but there are no check boxes against them. In that case what should i do ? Other wise let me know how to change the material master using a change number.

      Thanks,

      Rajesh.

    Hi,

    The revision level indicates a released processing status of a document. Later on, you can change documents that have a revision level with reference to either the change number or the revision level.

    Revision level assignment is automatic for documents when a version is released with reference to a change number for the first time. You receive a default value according to the predefined number sequence (Customizing).

    The revision level uniquely identifies a processing status of a document. You can only process a document version with reference to one change number, so you can only have one revision level per version.

    • Once you have entered a change number for a document info record and saved the document, you can no longer change the number.

    If you want to process the document at a later date with reference to a different change number, you must create a new version.

    Enjoy SAP….

    Don’t forget to give points if its useful ans.
