Currently I am working on a project where we are taking the data from an international company located in 10 different countries in Europe, that has one sub company per country. They each have there own ERP system and we are migrating these into SAP. Starting with Customer, Vendor and Material Master data. When you are building this many jobs obviously you want to start with building template tables and then later switch them to permanent tables.Because many of the table have fields with Unicode characters, it would be much easier to make every template table by default be set to nvarchar. Its easy to forget when you are in the process of building about 30 different Data Service Jobs.
I will create an enhancement request but it makes me a little sad in the short term, but such is life.
