No Acknowledgement from the e-Referral Service

Occasionally, an error creates a No Acknowledgement (NACK) status. To manage these errors:

  1. From Mail Manager , locate and highlight the referral under an eBooking Referral message type.
  2. Select the Audit tab.
  3. The audit trail shows no Acknowledgement (known as NACK): Added to Message Queue, Message ready for Transmission, followed by an error message. The message has a status of Processing error, rather than Sent. This may arise if the eReferral Service did not like the message for some reason, for example:
  • A file format which is not permitted (.doc, gif, .tif, .doctxt., xml, jpg are allowed).
  • A single attachment may be more than 1 mB (1mB is maximum per attachment).
  • Attachments may total more than 5 mB,
  • The Unique booking reference number (UBRN) is invalid (an unlikely scenario).

The Audit Trail should give a clue as to the error, for example:

  • Code - 0x80020009 Code meaning Exception occurred. Source = MCD Parser.MCD_ PARSER. 1 Description = GP2GP transformation failed. Reason; Destination Error. The attachment 0005008.rtf exceeds the maximum size of 1024 kbytes."

  • Another unsuccessful referral booking - this time the UBRN is invalid - an unlikely scenario
