What is the EDIFACT SUPRES message?

SUPRES is the UN/EDIFACT supplier response. The directory explains that a tourism operator sends a reservation message (RESMSG) to one or more service providers to request services, which may be subject to confirmation, and that the supplier response is the reply to that reservation.

The response confirms the requested services, offers alternatives such as a different room type, or declines the request. Operators rely on it to finalize packages and to tell customers what is confirmed, so every reservation should receive an explicit answer.

It usually follows RESMSG. Inside the UNB and UNH envelopes, the directory D.21A requires, in the start of message: BGM (Beginning of message). 5 conditional segment groups are listed by their trigger segment.How the EDIFACT SUPRES message worksSupplier response: who sends it, where it fits and what the directory marks mandatory1 WHERE IT FITSUSUALLY FOLLOWSRESMSGReservationSUPRESSENDERHotel, transportcompany or otherservice providerRECEIVERTour operatorCONTRL syntax report back, if agreedUSUALLY FOLLOWED BYNo business reply expected2 WHAT DIRECTORY D.21A REQUIRESInterchange: sender and recipient IDsUNB … UNZMessage SUPRESUNH … UNTSTART OF MESSAGEBGMBeginning of messageBODY AND SEGMENT GROUPS+ 5 conditional groups, starting with:RFFNADPAIPYTSEQBlue box: mandatory segment group.

How to read this diagram: the top row shows who sends SUPRES, to whom, and which messages usually come before and after it. The lower part shows what the directory D.21A itself requires: the envelopes around SUPRES and the segments and segment groups it marks mandatory. Conditional groups are listed by their trigger segment rather than drawn in full. This is the directory's minimum, not a trading partner's requirement: a message implementation guide, such as an industry subset or a partner’s own guide, usually makes some conditional groups mandatory, restricts the codes and may use an older directory.

Structure

Mandatory segments in SUPRES (directory D.21A)

In UN/EDIFACT directory D.21A, the SUPRES message has 75 segment positions arranged in 22 segment groups. These are the segments and segment groups marked mandatory at message level, in order; a mandatory group is shown with the segment that starts it. Segments inside conditional groups are needed only when the group is used. This is the directory’s requirement, not your trading partner’s: each partner’s message implementation guide names the directory it uses, often an older one such as D.96A or D.01B where the structure can differ, makes some conditional segments mandatory and restricts the codes.

  • UNH
  • BGM
  • UNT

Practical example

SUPRES in practice

A hotel receives a RESMSG for a family room but has only two connecting double rooms available for those dates. It sends the tour operator a SUPRES offering the connecting rooms at the same rate. The operator accepts the alternative and informs the family.

Implementation

Implementation considerations for SUPRES

  • Answer every reservation, including declines.
  • Reference the operator's reservation number.
  • State alternatives clearly so the operator can accept or reject them.
  • Keep room inventory in step with confirmed reservations.
