What is the EDIFACT DELJIT message?

DELJIT is the UN/EDIFACT delivery just in time message. The directory defines it as a message giving a customer the ability to convey precise delivery sequence and just-in-time schedule requirements to a supplier, intended to supplement the delivery schedule message (DELFOR).

Where DELFOR plans weeks and months ahead, DELJIT tells the supplier exactly what to deliver in the next hours or days, sometimes in the order in which vehicles will be built. Suppliers that deliver in sequence use it to load parts in line-side order.

It is usually followed by DESADV. Inside the UNB and UNH envelopes, the directory D.21A requires, in the start of message: BGM (Beginning of message) and DTM (Date/time/period) and body and segment groups: the required SG5 loop with SEQ (Sequence details). 5 conditional segment groups are listed by their trigger segment.How the EDIFACT DELJIT message worksDelivery just in time: who sends it, where it fits and what the directory marks mandatory1 WHERE IT FITSUSUALLY FOLLOWSDELFORDelivery scheduleDELJITSENDERCustomer, typically amanufacturerRECEIVERSupplierCONTRL syntax report back, if agreedUSUALLY FOLLOWED BYDESADVDespatch advice2 WHAT DIRECTORY D.21A REQUIRESInterchange: sender and recipient IDsUNB … UNZMessage DELJITUNH … UNTSTART OF MESSAGEBGMBeginning of messageDTMDate/time/periodBODY AND SEGMENT GROUPSMandatory group SG5 · repeats up to 9,999SEQSequence details+ 5 conditional groups, starting with:RFFNADPACLINBlue box: mandatory segment group.

How to read this diagram: the top row shows who sends DELJIT, 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 DELJIT 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 DELJIT (directory D.21A)

In UN/EDIFACT directory D.21A, the DELJIT message has 46 segment positions arranged in 16 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
  • DTM
  • SG5 (SEQ)
  • UNT

Practical example

DELJIT in practice

An assembly plant sends its cockpit module supplier a DELJIT every hour listing the modules needed for the next vehicles in build order, each with its sequence number and variant. The supplier builds and loads the modules in that order, and each delivery is announced with a DESADV before the truck arrives at the line.

Implementation

Implementation considerations for DELJIT

  • Process messages continuously; delays affect the production line.
  • Keep sequence numbers intact from receipt to loading.
  • Reconcile DELJIT call-offs with the DELFOR plan.
  • Monitor the connection closely, with fallback procedures for outages.
