Suppliers and service providers use this transaction set to communicate product or service notifications to customers, distributors, or other business partners. Typically sent in response to quality issues, service requests, or product updates, the notification includes detailed information about affected items and any corrective or repair actions. The BGN (Beginning Segment) establishes the notification’s purpose and date, the N1 loop identifies the parties involved (customer, supplier, service location), and the LIN loop details each affected product with its identification, description via PID (Product/Item Description), and associated quantities.

Consider a scenario where TechParts Manufacturing discovers a defect in a batch of industrial sensors supplied to AutoAssembly Inc. TechParts generates a 143 notification identifying the affected sensor model in the LIN segment, describes the defect using PID, and specifies the quantity impacted via QTY. The PRR (Problem Report) loop documents the defect details, while the REP (Repair Action) loop outlines TechParts’ proposed solution—such as replacement or firmware update—complete with corrected part dispositions in the PRT loop and associated costs in the ITA loop if applicable. AutoAssembly receives the complete notification with all contact information, making it possible to coordinate the remediation efficiently.
