When a record is created, I need to pull data from a custom field in the User table and store in the record. This code works for internal users but won't return for guest user.
LookUp(Users, User().FullName = 'Full Name', 'Work Site') // get work site name of current logged in user
I notice in the Users list, guest account First Name field stores a '#' and Last Name is the full name of the guest. Could this be the reason the lookup fails?
