This X12 Transaction Set contains the format and establishes the data contents of the Application Advice Transaction Set (824) for use within the context of an Electronic Data Interchange (EDI) environment. The transaction set can be used to provide the ability to report the results of an application system's data content edits. The results of editing transaction sets can be reported at the functional group, an entire transaction set, or any portion of a transaction set, in either coded or free-form format. It is designed to accomodate the business need of reporting the acceptance, rejection, acceptance with change, or partial acceptance or rejection of any transaction set. The Application Advice should not be used in place of a transaction set designed as a specific response to another transaction set (e.g., purchase order acknowledgment sent in response to a purchase order).
