  The customer ABS, JLMN is present in Quick books but still I get this error. This is not the only request while generating the request XML, there are other customers also with same properties. I am not getting any error for those customers. Can any one please let me know what can be the problem here?</p>
  
  <p><br/><br/> Is there any chance that my company file is corrupted? I am doing many InvoiceADD and CustomerADD requests with the company file as a part of my requirements. So could that be a reason for the problem here?
  <br/>
  Please let me know if you need any more information.
  <br/>Thanks.</p>
