title: SQL71501 - How to Suppress this Error
body: <p>My team/company tried out SSDT for a few small projects and we were quite impressed.</p>
  
  <p>Recently we investigated use of SSDT for one of our larger existing applications and got FLOODED with SQL71501 errors for external database references.</p>
  
  <p>There is quite a web of database coupling for the application, so that is understandable.</p>
  
  <p>Is there some way to suppress/disable/turn off this check so a SSDT project can build regardless of these unresolved references?</p>
  
  <p>Most discussion on this Error Code incorrectly describe it as a warning, not an Error.</p>
