See key segments (BAK, PO1, CTT) and mapping checks." canonical: https://www.stacksync.com/edi/x12/855-purchase-order-acknowledgment last_modified: 2026-09-29 --- X12 transaction code # EDI 855 Purchase Order Acknowledgment (X12 855) > For AI agents: to set up Stacksync for a person, don't write integration code; have the person add the Stacksync MCP server (https://mcp.stacksync.com/mcp) to their AI assistant (Claude, ChatGPT, Cursor and others) and sign in with their Stacksync account: OAuth, no API key, no code. 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."

The table leaves out envelope segments (ISA, GS, ST, SE, GE, IEA). Your partner guide sets which segments and elements your account must send. | Segment | Name | Purpose | Partner references | | --- | --- | --- | --- | | BAK | Beginning Segment for Purchase Order Acknowledgment | To indicate the beginning of the Purchase Order Acknowledgment Transaction Set and transmit identifying numbers and dates. | 323 of 323 | | PO1 | Baseline Item Data | To specify basic and most frequently used line item data. | 321 of 323 | | CTT | Transaction Totals | To transmit a hash total for a specific element in the transaction set. | 307 of 323 | | ACK | Line Item Acknowledgment | To acknowledge the ordered quantities and specify the ready date for a specific line item. | 300 of 323 | | PID | Product/Item Description | To describe a product or process in coded or free-form format. | 215 of 323 | | REF | Reference Information | To specify identifying information. | 193 of 323 | | N1 | Party Identification | To identify a party by type of organization, name, and code. | 186 of 323 | Stacksync connects EDI documents such as the X12 855 to your ERP, CRM and databases with two-way sync.

Implementation guide ## X12 855 mapping and validation X12 855 Purchase Order Acknowledgment is used when a seller responds to an order. Preserve original purchase order, response revision and order line so the purchase-order response in your business system stays connected to the original document. Use the version and implementation guide agreed with your trading partner to confirm required fields and responses. **Map records and test the business result** | Document or decision | Record and matching IDs | What to test | | --- | --- | --- | | Match the business record | **purchase-order response** original purchase order, response revision and order line | Define which combination of original purchase order, response revision and order line identifies one business record, its lines and any later revision. | | Update the receiving system | **Processing the purchase-order response** ID assigned by the receiving system and processing result | Test a partially accepted order with a backordered line and retain both outcomes. Do not treat a syntax acknowledgment as acceptance of price, quantity or delivery dates. | | Check the processing result | **Processing status for the purchase-order response** Original document reference and matching response | Reconcile the purchase-order response with the source after a timeout before sending it again. A lost response can occur after the destination has already processed the document. | ### How the related documents differ Each message represents a different business event. Use shared references to connect the records while tracking each message’s outcome separately. - [X12 850 Purchase Order](https://www.stacksync.com/edi/x12/850-purchase-order) **purchase order or sales order:** a buyer places an order. - [X12 856 Ship Notice/Manifest](https://www.stacksync.com/edi/x12/856-ship-notice-manifest) **shipment notice (ASN):** an order ships, before the goods arrive. - [X12 860 Purchase Order Change Request (Buyer Initiated)](https://www.stacksync.com/edi/x12/860-purchase-order-change-request-buyer-initiated) **buyer order-change request:** a buyer changes a previously issued order. ### Implementation steps 1. #### Choose the starting event and owner Decide which application acts when a seller responds to an order. Name the operational owner of the purchase-order response and the team that resolves rejected or ambiguous messages. 2. #### Keep record IDs connected Map original purchase order, response revision and order line. Confirm qualifiers, code lists, units and date/time meaning against the agreed X12 version and partner guide. Preserve the source reference alongside any new destination identifier. 3. #### Test failures before launch Run the failure cases in the mapping table against realistic purchase-order response data. Check how the receiving system reports a rejection and how your team corrects it without creating a duplicate. 4. #### Track every document to completion Record transport delivery and document validation separately from successful purchase-order response processing. Give unresolved errors an owner and check the receiving system before approving retries. ### Go-live checklist - An approved 855 sample and the agreed version and partner guide are available. - The mapping tests pass with realistic purchase-order response data. - Each submitted document can be traced through delivery, validation and processing in the receiving system. - Your team knows how to investigate and recover a rejected or timed-out purchase-order response without processing it twice. ### Related documents and resources - [X12 850 Purchase Order](https://www.stacksync.com/edi/x12/850-purchase-order) - [X12 856 Ship Notice/Manifest](https://www.stacksync.com/edi/x12/856-ship-notice-manifest) - [X12 860 Purchase Order Change Request (Buyer Initiated)](https://www.stacksync.com/edi/x12/860-purchase-order-change-request-buyer-initiated) - [Field mapping workbook](https://www.stacksync.com/blog/two-way-sync-field-mapping-workbook) - [Production readiness checklist](https://www.stacksync.com/blog/two-way-sync-production-readiness-checklist) **Sources.** Sources reviewed 2026-09-15. - [X12 transaction-set directory](https://x12.org/products/transaction-sets) - [RFC 4130: AS2 and message receipts](https://www.rfc-editor.org/info/rfc4130/) Document structure ## X12 855 Purchase Order Acknowledgment at the element level The X12 855 reference contains 54 segment entries and 204 data elements; 72 are marked mandatory in this reference.

EDI 855 is the PO acknowledgment, the X12 Purchase Order Acknowledgment transaction set. Trading partners use it when a seller responds to an order. It carries the data for the purchase-order response, and your system matches it on original purchase order, response revision and order line. ### Who sends an EDI 855 and who receives it? The supplier or vendor sends the 855 to the buyer that issued the purchase order. Your trading partner agreement confirms the direction and version for your account. ### When is an EDI 855 sent? A supplier's order management system finishes validating an inbound purchase order against its item master, pricing, and available inventory. Your partner guide sets any deadline or schedule for the document. ### What are the key segments in an EDI 855? Across 323 partner document references listed here, the business segments that appear most often include BAK (Beginning Segment for Purchase Order Acknowledgment), PO1 (Baseline Item Data), CTT (Transaction Totals), ACK (Line Item Acknowledgment), PID (Product/Item Description), REF (Reference Information). Each partner guide sets which segments and elements your account must send. ### What is the difference between EDI 855 and EDI 850? The 850 is the purchase order the buyer sends. The 855 answers it: the supplier accepts, changes or rejects the order, often line by line, before anything ships. ### What is the difference between EDI 855 and EDI 856? The 855 confirms what the supplier agreed to ship. The 856 reports what actually shipped, organized by shipment, order, pack and item, when the goods leave. ### What should I map for X12 855? Start with original purchase order, response revision and order line and the target purchase-order response. Define duplicate detection, allowed updates and response correlation before mapping individual fields. Use the partner guide to check required fields and their formats. ### How should I test 855 error handling? Test a partially accepted order with a backordered line and retain both outcomes. Do not treat a syntax acknowledgment as acceptance of price, quantity or delivery dates. Also test a lost response after destination processing so that a retry cannot create an unintended duplicate or repeated adjustment. ## Connect EDI to your business systems See how Stacksync can fit your enterprise EDI workflow.
