In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In Claude Code: `claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp`. Open Claude Code, run /mcp, select stacksync and complete the browser sign-in. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat." Setup for each assistant: https://www.stacksync.com/mcp.md A document ledger and stable line mapping let a supplier tell an 850 replay from an 860 that cuts a line already in production, and answer the partner from accepted outcomes. Author Alexis Favre · Co-Founder & CTO Published September 18, 2026 Read time 4 min read APP TIPS ## The operating decision Manufacturing EDI intake should preserve the identity and sequence of each customer order while separating document receipt from business acceptance. X12 850 carries a purchase order and 860 supports buyer-initiated changes. The partner agreement determines how those documents apply to the order lifecycle. Validate item references, units and existing production commitments before accepting a change. Reprocessing the same business request should not create another order, release or production requirement. Explore the complete [manufacturing integration and automation hub](https://www.stacksync.com/industry/manufacturing) for the systems and processes around this guide. ![Summary card: EDI 850 and 860 order revisions for manufacturers](https://www.stacksync.com/images/blog-highlights/icp-manufacturing-edi-850-860-order-revision-idempotency.webp) ## What this looks like in manufacturing A supplier receives an 850 purchase order, creates an ERP draft, and then sees the file delivered again after the sender experiences a connection problem. Later, an 860 reduces one line after material has already been issued. Transport receipt alone cannot distinguish a harmless replay from a consequential revision. The intake process needs a document ledger, a stable order-line mapping and a separate approval state for the change. The customer should receive the business response required by its agreed process, based on what the supplier actually accepted. ## Records, ownership, and update rules | Record | Owner | Operating rule | | --- | --- | --- | | EDI document receipt | Integration operations | Record partner, transaction type, interchange context, received time and the original document reference. | | Business order identity | Order management | Resolve customer PO and applicable release identifiers independently from transport envelope numbers. | | Line revision | Order management and planning | Preserve partner line identity and requested differences against the latest accepted order state. | | Business response | Customer operations | Prepare the agreed acknowledgment or change response from accepted outcomes rather than from transport success. | ![Record ownership diagram: EDI document receipt, Business order identity, Line revision](https://www.stacksync.com/images/blog-diagrams/icp-manufacturing-edi-850-860-order-revision-idempotency.webp) *Define the record owner and the rule before enabling updates.* ## Work through the process 1. 01 Confirm the partner’s order process Read the implementation guide and agree how original orders, changes, cancellations and repeat transmissions are represented. Identify the version and required response documents. Do not assume that every customer uses an 860 in the same way or that a repeated 850 always means new demand. 2. 02 Build a receipt and application ledger Keep document receipt separate from attempted validation, accepted order changes and response transmission. Associate each attempt with the same business request where appropriate. This lets an operator recover from an interrupted run without guessing whether the ERP transaction was already applied. 3. 03 Validate the revision against current work Match the customer, order and lines, then compare requested quantities, dates and item references with the accepted version. Route changes affecting released or completed production to planning. Preserve unaffected lines and record partial acceptance if the partner process permits it. 4. 04 Reconcile ERP state and partner response Confirm the accepted destination identifiers before marking the application step complete. Generate the agreed response from that result and track its delivery separately. If response delivery fails, retry the response rather than applying the order change a second time. ![4-step operating sequence: EDI 850 and 860 order revisions for manufacturers](https://www.stacksync.com/images/blog-diagrams-mermaid/icp-manufacturing-edi-850-860-order-revision-idempotency.webp) *Follow the operating sequence; unresolved exceptions return to a responsible reviewer.* ## Handle the exceptions explicitly ### An 860 arrives before its original order is available Hold the change with its references and investigate sequencing or missing intake. Do not create a guessed original order simply to make the change appear processed. ### A file is redelivered with different transport metadata Compare the business request and application ledger before creating demand. Envelope identity alone may not describe whether the commercial instruction is new. ### The partner cancels a line already in production Route the requested cancellation to the approved disposition process. A syntactically valid EDI change does not override production or commercial policy. ## What to verify before expanding - Replaying the same accepted purchase order does not create a second ERP order. - A line change updates the intended existing line without reassigning unaffected quantities. - A failed response transmission can be retried without repeating the business update. - Operators can distinguish received, validated, pending review, applied and responded states. ## Connect this process to the rest of your operation [Explore Stacksync EDI](https://www.stacksync.com/edi) and scope the records and actions against your actual systems.

Do not equate technical receipt or validation with commercial acceptance. Follow the partner’s agreed acknowledgment process and represent the supplier’s actual business decision separately. Should the EDI document number be the ERP order key? Use a deliberate cross-reference between transport documents and business-order identity. Multiple documents can relate to one order, and one order may contain several releases or revisions. How should the first EDI pilot be tested? Use an original order, a harmless replay, a line change, an out-of-sequence change and a response-delivery failure. Inspect both the ERP records and the processing ledger after each case.
