The EDI 830 Planning Schedule is how manufacturers tell their suppliers what to build and when, across weeks or months, against a single blanket purchase order. Instead of cutting a fresh 850 for every shipment, the buyer sends a rolling 830 that carries both firm release quantities and forward-looking forecast. Reading it correctly is the difference between shipping on time and either sitting on dead inventory or missing a line-down deadline.
This guide covers what the 830 contains, how to tell forecast from firm, the segments you will work with, a real example you can open in our renderer, and how a supplier handles inbound 830s even without an ERP integration.
What Is an EDI 830?
An EDI 830 is the Planning Schedule with Release Capability transaction defined by the ASC X12 standards body, used by a buyer to send a supplier forecasted and firm demand for materials over a defined horizon. It is most common in manufacturing supply chains, where an OEM issues a blanket PO and then drives shipments through successive planning schedules rather than individual orders.
Authoritative references for 830 implementation:
- The X12.org Transaction Sets reference defines the BFR, LIN, FST, and SHP segment structure used across 830 implementations
- The EDI Academy 830 and 862 reference explains how the 830 carries forecasting and material-release information, and how the 862 Shipping Schedule supplements it for near-term ship instructions
Who sends it? The buyer (an OEM, assembler, or other manufacturer) sends the 830 to its supplier or contract manufacturer.
When is it sent? On a regular cadence, often weekly or daily. Each new 830 supersedes the prior schedule for the same item and ship-to.
Why does it matter? The 830 is the demand signal that drives production planning and raw-material purchasing on the supplier side. Misreading a forecast bucket as a firm release (or the reverse) leads directly to over-build, stockouts, or premium freight.
Forecast vs Firm: the Distinction That Matters
A single 830 usually carries two kinds of quantity in its forecast (FST) segments, and the whole point of the document is to separate them:
- Firm / committed releases are authorized for shipment. The supplier should produce and ship these to the dated requirements. In X12 these typically carry a forecast qualifier such as
C(firm). - Planning / forecast quantities are a heads-up so the supplier can buy materials and reserve capacity. They are not yet authorized to ship and can change in the next schedule. These typically carry a qualifier such as
D(planning).
Some 830s also carry cumulative (period-to-date) quantities so both sides can reconcile what has shipped against what was authorized. When an 830 is used as an order-release mechanism against a blanket PO, those releases replace discrete 850s entirely.
Key Segments Explained
Here are the segments you will work with in an 830 transaction set:
| Segment | Name | Purpose |
|---|---|---|
| ST | Transaction Set Header | Identifies the start of the 830 and assigns a control number |
| BFR | Beginning Segment for Planning Schedule | Schedule type, purpose, the buyer reference (often the blanket PO), and the horizon start and end dates |
| N1 | Name | Identifies the buyer location (MI), supplier (SU), and ship-to parties |
| LIN | Item Identification | The part being scheduled, by buyer part number and supplier part number |
| UIT | Unit Detail | Unit of measure and, where present, price |
| PER | Administrative Contact | The buyer-side planner or MRP controller responsible for the schedule |
| SDP | Ship/Delivery Pattern | The pattern that ties forecast quantities to dates |
| FST | Forecast Schedule | The dated quantity buckets, each flagged firm or planning |
| SHP | Shipped/Received | Cumulative shipped and received quantities for reconciliation |
| CTT | Transaction Totals | Number of line items in the schedule |
A Real EDI 830 Example
The example below is an OEM planning schedule for a molded part against a blanket PO. The first three weekly buckets are firm releases (code C); the later buckets are planning forecast (code D). Open it in the renderer to see the parsed structure and plain-English view.

Where the 830 Sits in the Order Lifecycle
In a blanket-PO manufacturing relationship, the 830 often replaces the per-order 850:
- Blanket 850 Purchase Order - Buyer establishes the agreement, pricing, and item list
- 830 Planning Schedule - Buyer sends rolling forecast and firm releases against that blanket
- 862 Shipping Schedule (optional) - Buyer sends tighter near-term ship instructions
- 856 Ship Notice / ASN - Supplier notifies the buyer of each shipment
- 810 Invoice - Supplier requests payment
A late or misread 830 ripples through every step that follows, which is why production planners watch it closely.
How Suppliers Handle Inbound 830s Without an ERP
Many of the suppliers receiving 830s are contract manufacturers, job shops, and molders that do not run a system with an affordable EDI-capable API. The common (and expensive) advice is to integrate the planning schedule directly into an ERP, but that is not the only path.
OrderSync reads inbound 830s (and arbitrary-format demand like PDF, Excel, and email release schedules) and turns them into a clean, reviewable list of dated release requirements. It separates firm from forecast, collapses weekly grids into dated lines, flags anomalies, and produces valid X12 that drops into the EDI desktop client or folder your trading partner already polls. No ERP read or write is required to get started. When you are ready, the same pipeline can validate releases against your item and ship-to master.

Frequently Asked Questions
What is the difference between EDI 830 and EDI 850?
An 850 is a discrete purchase order for a specific set of line items. An 830 is a rolling planning schedule against a blanket agreement that carries both firm releases and forward forecast. In many manufacturing relationships the 830 replaces repeated 850s.
What is the difference between EDI 830 and EDI 862?
The 830 carries the longer-range plan, including forecast that authorizes material and capacity. The 862 Shipping Schedule is a tighter, near-term instruction for what to ship and when. The 862 supplements the 830; it does not replace it or authorize resources on its own.
How do I tell forecast from firm in an 830?
Look at the FST forecast qualifier on each dated bucket. Firm, ship-authorized quantities and planning-only forecast quantities use different codes (commonly C for firm and D for planning). Treating planning forecast as firm is the most common and costly 830 mistake.
Can a supplier process an 830 without an ERP?
Yes. The 830 can be parsed, reviewed, and acted on as a schedule of dated requirements without writing into an ERP. OrderSync ingests 830s and other formats, surfaces the releases for review, and outputs valid X12 to your existing EDI client.
