Trying to create a mass update of a 35,000 item SharePoint list when a supervisor changes. However, I have learned that collecting the items in the list where the Supervisor = user name (people data type) does not work… it is actually filtering on the hidden SharePoint User Information List ID found in the site collection. So, I am looking for a Nintex workflow that to lookup the User Information List ID in this hidden list based on the user login name.
so here is the link to the list:
<site>/_catalogs/users/simple.aspx
Any suggestions are welcomed!
