UnhandledSystemException-SaaSException Unhandled system exception: Access is denied. You need to log in the Report Manager Role to edit a Report Template.
This issue is related to the ReportManager role being deleted from the HEAT system and recreated incorrectly. HEAT requires that the ReportManager role name be exactly entered as the role name in Configure Application >> Users and Permissions >> Roles and Permissions. If the role is named Report Manger instead of ReportManager, HEAT will not recognize the role and return the access denied error.
