title: SSAS cube processing error about column binding
body: <p>This is an error message I get after processing an SSIS Cube</p>
  
  <p><code>Errors in the back-end database access module. The size specified for a binding was too small, resulting in one or more column values being truncated.</code></p>
  
  <p>However, it gives me no indication of what column binding is too small.</p>
  
  <p>How do I debug this?</p>
