What is the ANSI X12 EDI 865 T-Set?

The ANSI X12 EDI 865 transaction set, commonly referred to as the Purchase Order Change Acknowledgment/Request, serves as a formal communication tool between sellers and buyers, specifically addressing the changes in a purchase order. It plays a pivotal role in the purchasing process by allowing sellers to confirm, request changes, or reject changes made by the buyer to the purchase order.

Essentially, the EDI 865 T-set acts as a bridge for negotiations and agreements on purchase order changes. It ensures that both parties are aligned on the terms of the purchase, including quantities, prices, and delivery schedules. 

What are the benefits and use cases for the ANSI X12 EDI 865 T-Set?

Let’s look more closely at the specific benefits and applications for the ANSI X12 EDI 865 T-Set.

CTT	CTT1100~	Transaction Totals: Provides a summary of the transaction, such as the total number of items and the total quantity.
SE	SE90001~	Transaction Set Trailer: Indicates the end of the transaction set and provides the total number of segments included and the transaction set control number.

How is an ANSI X12 EDI 865 T-Set processed?

There are several crucial steps that go into processing an ANSI X12 EDI 865 T-Set:

1. Receipt of EDI 860: The process begins when the seller receives an EDI 860 transaction set from the buyer, indicating a request for changes to a previously issued purchase order.
2. Review of requested changes: The seller reviews the requested changes in the EDI 860. This review process may involve checking inventory levels, production capacity, and the feasibility of meeting the new delivery schedules or specifications.
3. Preparation of EDI 865: Based on the review, the seller prepares an EDI 865 transaction set. This document can either acknowledge the acceptance of the changes, reject them, or propose alternative adjustments.
4. Inclusion of detailed information: The EDI 865 includes detailed information about the changes being acknowledged or requested. This can involve adjustments in prices, quantities, delivery dates, or product specifications.
5. Internal approvals: Before sending the EDI 865, the proposed changes or acknowledgments may need to go through internal approval processes within the seller’s organisation to ensure that they are feasible and align with business strategies.
6. Transmission of EDI 865: Once approved, the EDI 865 is transmitted back to the buyer. This transmission uses secure EDI communication protocols to ensure the data’s integrity and confidentiality.
7. Receipt and review by buyer: The buyer receives the EDI 865 and reviews the contents. If the seller requested further changes, the buyer would evaluate these proposals in the context of their needs and constraints.
8. Buyer’s response: Depending on the situation, the buyer may respond with another EDI transaction set. For example, if the seller proposed alternative changes, the buyer might send an EDI 860 to accept, reject, or modify those proposals.
9. Finalisation of changes: Once both parties agree on the changes, they finalise the adjustments to the purchase order. This agreement may be documented with a final EDI transaction confirming the agreed-upon changes.
10. Update of internal systems: Both the buyer and seller update their internal systems, such as inventory management, production scheduling, and financial systems, to reflect the finalised changes to the order.
11. Fulfilment and shipping: The seller proceeds with the fulfilment and shipping of the order according to the revised terms and conditions, as documented in the EDI 865 and subsequent agreements.
12. Documentation and record-keeping: Both parties keep records of the EDI transactions for future reference, auditing, and compliance purposes, ensuring a clear trace of the communication and agreements made.
