title: After many attempts, The report server cannot process the report or shared dataset
body: <p>We have an SSRS report that connects to an SSAS cube. The report and the Data Source (to the SSAS cube) had been deployed. Unfortunately, nobody could see the report (error: either the user does not have access to the DB or the DB does not exist).</p>
  
  <p>After many changes to the datasource, I deleted the datasource and I received a <code>rsInvalidDataSourceReference</code>, which is correct. I then deleted the report.</p>
  
  <p>Once I deleted both of them I cleared IE's cache. Then I redeployed both the report and the datasource, and went to the report's properties to make sure it was pointing to the correct datasource. I have not made any changes to the datasource so I should now get the user access error.</p>
  
  <p>Unfortunately, I continue getting an <code>rsInvalidDataSourceReference</code>. I've done this many times (deleted &amp; redeploying datasource and report) but still nothing.</p>
  
  <p>What can the problem be? At the very least I should get denied connection error once again.</p>
