Manufacturer coupon issuers use this transaction set to communicate family code structures to their trading partners, typically retailers or coupon clearinghouses. The 877 is sent in response to requests for coupon family classification data and defines how manufacturer coupons are organized into hierarchical family groupings. The transmission begins with the ST (Transaction Set Header) and BGN (Beginning Segment) segments to establish context, includes N1 (Name) segments to identify the parties involved, and uses DTM (Date/Time Reference) to mark the effective date of the family code structure. The document’s core content is organized through ENT (Entity) segments, which introduce each family code category, followed by hierarchical LIN (Item Identification) segments that specify individual coupon items within those families.

Consider a scenario where Procter & Gamble submits an 877 transaction to a major retailer’s coupon processing center. P&G uses this document to define that coupon family code “HEALTH-ORAL” contains multiple coupon line items, each identified through LIN segments with unique item numbers for toothpaste products, mouthwash products, and dental floss products. Within each LIN segment, optional G28 (Line Item Numbers) and G69 (Line Item Detail – Description) segments provide additional classification codes and descriptive text to ensure the retailer’s system correctly recognizes and categorizes each coupon for proper validation and redemption processing. This structured approach allows retailers to maintain accurate coupon family hierarchies without manual data entry.
