I've enabled Custom Fiscal Year in a Sandbox, in an attempt to set the first day of week as Saturday (requirement from client).
The structure I've chosen is 12 month / year Gregorian. When I preview the calendar under Custom FY, it shows Saturday as the first day of the week:
However, when I go to Reports and choose the reporting period as This Week, it automatically selects the week starting with a Sunday:
Is any additional configuration required anywhere to achieve the Saturday-first day configuration in Reports? What am I missing here?
