If the admin user has set up various business events and automations, whenever these run, they will get tagged with the admin user as the “owner” or “last modified by” user.  I don’t think I’ve noticed those updating the access history in the past, but I’ve had questions about why the admin user is associated with specific transactions in the past.
 

Hi @meganfriesen37

I noticed that the system collects all the screen usage activities of other Users and records them to the User admin even though the User admin actually has no Sign-in and no actual usage activity during this period. 

I’m not sure that my assumption is correct so I’d like to ask the Acumatica experts again.

Hi @nhatnghetinh  - 

Based on my knowledge of how autoamtions/business events run, they all call the admin user account behind the scenes to handle internal steps.

So I would assume this looks something like:
User 1 Saves Invoice

Automation/Business Event triggers

Admin user does something (as part of Business Event/Automation logic)
 

It’s the same general reason as why the admin user needs to have roles to access any restricted roles/branches if you’re using role based restrictions or you risk automations failing to fire properly.
