title: Error Syncing DOORS to Rhapsody using the Gateway Tool
body: <p>I am using the Rhapsody Gateway tool to synchronize my DOORS requirements with my Rhapsody model, and I get the following error:</p>
  
  <p><em>Some errors occurred:
  Failed to move requirement_id under Requirements Doc
  Exception while synchronizing requirement requirement_id</em></p>
  
  <p>I get the same error for approx. 10 requirements out of several hundred - so most are syncing fine.</p>
  
  <p>I've done a search on the web, but have not seen anyone experiencing the same error.  Does anyone know what could cause this error?</p>
  
  <p>DOORS version 9.1.0.0
  Rhapsody version 7.6.1.1</p>
