Problem:

Why might I see duplicate issue numbers in the Issue Manager GUI or Database?

Resolution:

ANSWER
----------------------------------
Duplicate issue numbers may be created if users continue to create issues during an upgrade or when a database is being imported.
This will happen because during an import the appsetting table containing the current highest DefectID is imported first then the import of the Defects themselves starts (this may take some time). If a new issue is entered between importing the appsetting table and finishing the defect import the appsetting table is no longer up-to-date. Therefore the system will think that it can use numbers from the appsetting table in sequence even though those numbers have already been allocated in the DefectID table.

To avoid this happening ensure that no users attempt to log new issues during a database import.

If you experience this issue please contact support before attempting to delete or change duplicate database entries. Failure to do so could result in database failure.
