Good day and thank you for your interest.
We have a business requirement to configure the Support Case entity on multiple Portals ( Customer Self-Service & Employee Self Service). The main requirement is to determine whether the Subject Tree can be configured differently for each portal; Some subjects to be displayed only on the Customer Self Service portal and some to display only on the Employee Self Service Portal.
I wasn't able to determine a way to do this natively via the subject tree configuration in Dynamics 365 Administration settings. Kindly share any solution suggestions. Humble Regards
