Import DDL Script (EA build 1721) - SQL Server (Azure SQL)

[robert.daniels-dwyer@hs2.]

We are trying to import DDL into a SQL Server repository (running on Azure SQL on our own tenant).  We are getting an uncontrolled error with t_xref.  Sparx then creates the names of the first two tables in the .sql file, but no columns, and crashes out. 
We do not get this error when loading onto a local file-based repository.

Has anyone come across this?  Does anyone have any ideas?
