Error No 00055 appears when trying to add any objects to SMARTEAM.
Error No: 00055
The item already exists in the system. Adding item '<ID>
<REVISION>' caused a duplicate value error in '<CLASS>'
In order to correct this issue first have everyone log out of SMARTEAM.
Then make a backup of the database.
Then go into the <SMARTEAM>\Bin directory on the server and run the
SmartDbRepairing.exe file.
Login with a user that has Administrative Functions in SMARTEAM.
With the SmartDbRepairing tool open, select Actions > Fix Last Object IDs
> Yes and let it run.
After the SmartDbRepairing tool has finished running, see if the issue has been
resolved.
If the issue still occurs then run Data Model Designer on the database.
Launch Data Model Designer and then click File > Modify Database Structure
and then just click Create and let it go through.
