The ANSI ASC X12 transaction set specifically utilized for Payment Order/Remittance Advice is the ANSI ASC X12.820. This transaction set is designed to facilitate automated payment processing, allowing for an effective exchange of payment information between trading partners. It encompasses details necessary for processing payments, including the amounts, invoice references, and processing dates, thus ensuring clarity in the remittance advice associated with payments.

Understanding this transaction set is crucial for ACH operations, as it streamlines the reconciliation process for entities receiving payments, thereby enhancing operational efficiency. The other options, while related to electronic data interchange, serve different purposes. For instance, ANSI ASC X12.835 is utilized for Healthcare Claim Payment/Advice, focusing on payment details specific to healthcare transactions, while ANSI ASC X12.521 and ANSI ASC X12.823 have their own specific applications that do not pertain to payment orders and remittance advice. Thus, recognizing the correct transaction set crucial for ACH professionals ensures accurate processing and compliance within the financial transaction ecosystem.
