the role of Management ID

Hi

i want understand the role of "Management ID"

I read thatin theBIadministrationguidebutI can notunderstand the purpose ofthis parameter

Note:

The Change Management ID is used for obtaining information related to logging, auditing, job history,

and so on. The promotion management tool enables you to map each instance of job creation to a

Change Management ID. The Change Management ID is an attribute that is set by the user in the

job definition while creating a new job. The tool automatically generates an ID for each job.

thanks
