title: Errors in the high-level relational engine (SQL Server)
body: <p>I made changes to a SQL Server table and when processing my cube I get these errors:</p>
  <blockquote>
  <p>Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Channel Final', Name of 'Channel Final'</p>
  </blockquote>
  <p>My question is: if I change column names of a table, how can I change the names of that table in the cube so that I don't get that error?</p>
