Unable to change the “"Next Run Time" of a scheduled report. No error messages just the “Next Run Time” is not changed. This occurs for some of "Run Object" options. With Run Object set to “Once” the problem does not occur, but with it set to “Nth Day Of Month” or “Last day of Month” or “1st Monday of Month” etc… you cannot reschedule and change the “Next Run Time”
Create a recurring scheduled report using CA reports - Asset - Group - "Current Ports Summary: Group" for example
Run Object: Nth Day Of Month
Start date/time : 06:00 AM 8/01/2017
Now schedule it. Then open history and Reschedule it, in the Recurrence specify
Start Date/time: 01:00 AM 8/01/2017
Click on Schedule and check the “Next Run Time”. It will be unchanged.
