Model Validation Error P1033 - Constraint name is not unique

Apr 9, 2012 at 4:01 PM

I have a model that has no validation errors on VEA 2005 (Visio 2003). When I open this model in Visio 2010, it shows me many validation errors: 

error P1033: "index_name" : Constraint name is not unique. The target DBMS requires the constraint name to be unique in the database.

These indexes are basic non-unique indexes without any attached constraints. Obviously, the SQL server does not require unique index names per database. Why am I getting this message? Any help is greatly appreciated.
