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.
There should be no quotes since it is a SQL Server function.
Tested on TDM portal version 4.9.361
Release : 4.9.1
Component : TDM Web Portal
TDMWeb-4.9.378.0.zip resolves this issue.
