Use ACL debugging tools in service portal or angular pagesIssue After enabling ACL debugging, you can impersonate another user to see what ACL rules the user passes and fails. When you impersonate a user, you can only see what that user is allowed to see. For example, you cannot view a record that an ACL prevents the user from seeing. While using the Desktop UI the ACL rule output messages will be displayed at the bottom of the page or form you're seeing, however, if they'll not be displayed on a Service Portal page. For that, we can use the page /ui_page.do to get the rule output messages. ResolutionThe Steps to accomplish this: 1 - as an admin user, enable ACL rule debugging by navigating to System Security > Debug Security Rules 2 - impersonate the user with which you want to debug ACL rules 3 - load the page where you want to debug 4 - right after loading the previous page, open a new tab with /ui_page.do the ACL rule output messages from the portal page will be captured and displayed on the ui_page page. After this you can debug the ACLs according to the documentation below: ACL debugging tools
