Thank you for contacting us.
The issue you experience appears when any of the identifiers (table names, constraint names, sequence names, and etc.) in the generated DDL script are longer than 30 characters. In this connection, my best guess about the cause on your side is that the name of the constraint related to the created association becomes longer than that. The recommended way to resolve the error is to shorten the names of the participating tables in the mapping configuration.
Another option is to update Telerik Data Access on Monday (December 15th, 2014), because in this upcoming release, we utilize a new algorithm for generating the constraint names. This algorithm makes sure that the constraint names never exceed the 30 character limitation but are unique.
I hope this helps. Do let us know if you need further information or assistance.
