It is quite hard developing and then verifying that some 45+ SQL searches work as expected across all of the various database servers that Sparx Enterprise Architect supports, particularly when some like MS SQL server are paid-for proprietary software which I don't possess (this is where I rely on users identifying bugs). As an unfortunate consequence of not having SQL Server it seems as though some of the searches triggered by the model views are causing errors to be thrown.
I think now, however, that I've managed to solve all but 1 query (Most Relationships - All) so that they run without error on MS SQL server. Just need to finish checking it out.
A house-keeping update to the MDG for TRAK 127 should be released soon. Thereafter the next release is likely to incorporate a new TRAK viewpoint (Assurance).
