I get an error message 'This report has already been scheduled'. How to solve this?

When you schedule a report, a unique object is created through a single request. The error you received can occur, when the same request is re-initated and when the same object is referred. To avoid the error, refresh the KPI by selecting it from the KPI browser and use ‘Schedule Mail’ feature while subscribing to the report for the second time.
