title: Cannot delete SAP Change Request due to locked objects
body: <p>Im trying to delete a SAP CR.
  I opened it for some changes. Now I don't need these changes anymore, so I deleted all the objects and I cleared all the components of my CR.</p>
  
  <p>Then I tried to delete the request (it is empty now) but an error occured:</p>
  
  <pre><code>Cannot delete (request locks still exist)
  </code></pre>
  
  <p>How can I fix it? My CR is empty... Where are locks?</p>
