I am running Sage 50 Premium Accounting with Payroll version 2021.1 and trying to roll over to a new year.  When I go into Maintenance -> Start new year.  The error that comes up is:  Sage 50 - Duplicate Entry.  You have entered a value that has been assigned to another record.  You cannot have two records of the same value.  An error occurred while moving current year's data to last year.  As a result, the new year could not start.

When I went into Advanced Database Check, it did not find any issues:  The Sage 50 database verification tool did not find any problems with your company file.

Please help if anyone could give advise or instructions.

Thanks 

Peter
