What is the "update_guid" field used for?

[bonsai]

The "update_guid" in the update set data contains a sys_id.

Which record is this sys_id?

Which TBL is it managed in?

Hi @bonsai ,

looks like this is extension to your below post  

https://www.servicenow.com/community/sysadmin-forum/what-is-the-quot-update-guid-history-quot-field-...

as mentioned in that post 

update_guid holds the latest GUID of update_guid_history

or I think update_guid is generated first and added to update_guid_history

I have tried to find if that GUID leads me to any table using sysid command in the SNUTILS but I couldn't any associated table or record for that GUID

so may be as mentioned by @Maik Skoddow it's for the servicenow to keep track of something

Please mark my answer as helpful/correct if it resolves your query.
