In the TDM portal, when the default value of the table field is NEWID() (on SQL Server), the insert generated in the SQL file puts the value between quotes.
This causes an error when the insert is executed.
Release : 4.9.361
Component : TDM Web Portal
There should be no quotes since it is a SQL Server function.
TDMWeb-4.9.378.0.zip and later resolves this issue.
