Queue job ReportingTimesheetPeriodSync failed

Hi,

I'm using Project Server 2010.

I've Closed some Timesheets Reporting Periods (option Server Settings, Time Reporting Periods), because we have just closed the fiscal year and everything has already been reported, and I've received 29 emails with this error (for different Periods, 29 periods)

I've been looking inside the Stored Procedure MSP_Epm_SyncPeriodInTimesheetProject and it is very simple, it returns an error -1 because it doesn't find a record:

IFNOTEXISTS(SELECT TaskUIDFROM dbo.MSP_EpmTaskWHERE ProjectUID ='0000cf75-fb12-4ffc-a404-aec4f3258a9c'

AND TaskUID= @PeriodUID)

  BEGIN

     RETURN-1

  END

Do you know how to solve this problem?

Thank you and regards,
