Please, I need an explanation of the date and date/time fields of the 'cmdb_ci_service' table.

i.e. in wich cases a configuration item takes on the values shown below for the date and date/time fields of the 'cmdb_ci_service' table during the life cycle?

Looking at your questions from the last couple of days: why are you asking us to do your work for you? It looks like you are required to deliver some kind of document and don't wont to use google yourself.

You do know ServiceNow has a docs-site where tables and fields are explained?

Hi Mark, maybe I already searched the documentation and couldn't find the answer, what do you think?
otherwise I wouldn't have asked the question in the community if I already had the answers to my questions.
please can you share with me the doc-site where the fields of the cmdb_ci_service table are explained?
