Error in Analysis while trying to add schedule name to time and absence report

Summary:

We have created an analysis using "Workforce Management - Processed Time Cards Real Time" subject to fetch employee details, department, and time entries with processed hours. We would need employee shift details(schedules) in the report for additional analysis from the business end.

But as soon as I add Schedule Name from "Workforce Management - Person Real Time", I get an error saying 'No fact table exists at the requested level of detail'.

Is there a way we can add the schedule name to the time card report?
