Customer created a customized role in DDC, which aims to allow this delegated admin role to perform all actions under Trends and Filters in Director.
Initially, the role definition of Director only included "Director - View Filters Pages" and "Director - View Trends Pages".


The problem is, an error message is shown when this delegated admin attempts to generate reports under Director - Trends - Custom Reports.

Error details:
"Unexpected server error. View Director server event logs for further information".



In Windows Event log from Director server, event id 6 "An unexpected error occurred - Parameter received is null or empty Siteid" is exhibited. 

Problem Cause

Role assignment for the delegated admin account is insufficient that is incapable of report generation in Director.
