Error saving Global Template

[Robin Roe]

Hi

Just wondering if anyone knows how to fix this error. It appears when I save
the Enterprise Global template. I think it is trying to do something with the
Enterprise Resource Pool, as this remains checked out after the error occurs.

I have ammended the Standard Calendar to represent our organisation's hours.
The resources use the same calendar.

[Microsoft][ODBC SQL Driver][SQL Server] Cannot insert duplicate key row in
object 'MSP_CALENDARS' with unique index 'I_MSP_CALENDARS'.

Thanks
