Exporting a Data-tier application from SQL Server using SSMS has a problem

According to MSDN (  it is quite simple to Export a data-tier application. Here is an overview of exporting a database as a Data-tier .bacpac file which can be deployed to another server.

Looks like some implied incompatibility with some Microsoft Azure SQL database. It may be noted that the target file was supposed to be saved to the local disk and not Microsoft Azure.

This happens in SQL Server 2014 as well.

According to a recent MSDN forum post, the failure in SQL Server 2012 and SQL Server 2014 for this particular case of Northwind database is perhaps related its
