IT redesigns the report and handover it back. • Report is not working because of the data issue in the previous layers. • Users wants to add some advance functionality in the report like time intelligence, currency conversion etc. • User is new to the environment and needs more understanding/access on power bi and what all we already have there.

How to Debug a issue • First we need to be a member of workspace otherwise we don’t see. • We get message if the schedule refresh for the report is failing. • Try to replicate the issue in the power bi service. • Download a copy of the report to local computer and try browsing it in power bi desktop. • Try to identify the error, may require changes in the report. • After everything is working fine, republish the report. • Check in the power bi service and ask user to check again.
