How does HublerX receive the OEM sequence call-off?

HublerX reads the sequence call-off via EDI (EDIFACT DELFOR, ANSI X12 830, or ODETTE), via the OEM's supplier portal, or via a structured file (XML, CSV). The call-off is loaded automatically — no manual transcription. Call-off revisions received during production are flagged immediately with the positions affected.

What happens if a call-off revision is received while production is in progress?

HublerX compares the revision against the current production sequence and identifies the positions affected by the change — positions already completed, positions in production, and positions not yet started. The planner sees the impact immediately and can decide whether to stop and resequence, or flag the revision to the OEM as unachievable within the remaining window.

Can HublerX handle multiple part variants in the same call-off?

Yes. Sequence call-offs for complex parts — seats with multiple fabric, colour, and specification combinations — are handled position by position. Each position's required variant is communicated to the production operator individually, and the scan verification checks the exact variant code, not just the part number.

How does HublerX support the SILS (Sequenced In-Line Supply) and SILS2 delivery models?

HublerX supports SILS (supplier produces in OEM sequence from a frozen call-off) and SILS2 (supplier receives sequence trigger from OEM line and delivers within a fixed time window). The call-off intake, production sequencing, and ASN transmission are configured to match the OEM's specific SILS variant.

Sequenced Delivery Management

The Problem

Parts arrive at the OEM line in the wrong sequence. The assembly line stops. The penalty is immediate.

Sequenced delivery to an automotive OEM assembly line means every part must arrive in the exact order in which it will be fitted to a vehicle on the assembly line. A seat supplier delivering to Maruti Suzuki's Manesar plant knows that the seats for vehicle sequence positions 1 through 48 must arrive on the truck in exactly that order — because the assembly line robot or operator picks the next seat from the front of the delivery rack. If position 12 and position 13 are swapped, the assembly line stops.

A sequencing error that causes a line stop is one of the most expensive quality failures in automotive supply — line stop penalties can reach ₹2–10 lakh per hour depending on the OEM. The sequence call-off is received hours before delivery. The production sequence must be executed exactly as called. Any deviation — a part produced out of order, a packing error, a loading mistake — results in a sequence violation.

Current Workaround

What most operations do today: Most sequenced delivery operations today: the sequence call-off is received and printed. The production team works from the printed sequence sheet. Sequence position is tracked on paper or in a spreadsheet. The packing team checks the sequence manually before loading. Sequence verification at the loading dock is a visual check against a printed list — accurate for the first 10 positions, unreliable for positions 40–48 at the end of a shift when attention degrades. Sequence errors are typically discovered at the OEM receiving dock or, worse, at the assembly station.

The HublerX Approach

Sequenced delivery management is a synchronisation problem — the OEM's production sequence must drive the supplier's production sequence, the pick sequence at packing, and the load sequence on the truck. Every part must be verified against its sequence position at every stage. HublerX reads the OEM sequence call-off, drives production in the correct sequence, verifies each finished part against its sequence position at packing, and confirms the complete rack sequence before the truck is released — eliminating sequence errors before they leave the supplier's plant.

How HublerX Coordinates It

The step-by-step sequence

1
OEM sequence call-off received and loaded
HublerX reads the OEM's sequence call-off — the vehicle production sequence, the part variant required for each sequence position, and the delivery window. The call-off is converted into a production sequence list that drives the production line.
On call-off receipt · typically 4–8h before delivery
2
Production sequence driven from call-off
HublerX releases work instructions to the production line in the exact sequence required by the OEM call-off — each sequence position with the part variant, colour, specification, and any vehicle-specific configuration. The production operator receives position-by-position instructions, not a batch production order.
On production start
3
Each part verified against sequence position at production
As each part is produced, it is labelled with a sequence position barcode and scanned to confirm it matches the required part variant for that position. A mismatch triggers an immediate alert — the wrong variant has been produced for a sequence position and must be corrected before the sequence continues.
At each production completion
4
Packing sequence verified against call-off
At packing, each part is scanned in sequence as it is placed in the delivery rack. HublerX verifies that each scan matches the expected sequence position and the correct part variant. A packing error — wrong part, wrong position — is flagged before the rack is sealed.
At packing
5
Full sequence verified before truck release
Before the truck is released for delivery, HublerX generates a sequence verification report — confirming that every rack in the load matches the OEM call-off, every sequence position has the correct part variant, and the load sequence matches the delivery rack order required by the OEM. The truck is released only when all checks pass.
Before truck release
6
Sequence ASN transmitted to OEM
On truck departure, HublerX transmits the sequence ASN to the OEM — with each sequence position, the part serial number, the variant, and the delivery reference. The OEM's receiving system can verify the incoming sequence against the ASN before the truck reaches the dock.

Outcomes

At production

Sequence errors caught at the production scan — before packing, before loading, before the OEM dock

100%

Every part scanned against its sequence position — no visual check or paper list required

Full verify

Complete sequence verification before truck release — not a sample check of the first few positions

Automatic

Sequence ASN transmitted to OEM on truck departure — no manual EDI step

Results are directional. Sequence error prevention depends on consistent barcode scanning at production and packing, and the accuracy of OEM call-off data.
