This transaction set is a Motion Picture Booking Confirmation sent by distributors or booking agents to theater chains and cinema operators to confirm the booking details of films across multiple screens and locations. It confirms essential booking parameters established during the negotiation phase and is typically sent in response to a booking request or order. The transaction uses the BGN (Beginning Segment) to establish the confirmation context, the LX (Assigned Number) to organize booking information into logical groups, and the THE (Screen Theater Identification) segment to specify individual theaters and screens where films will be shown, along with related details such as geography, currency, and language requirements.

Consider a scenario where Paramount Pictures confirms a booking with Cineplex Entertainment. Paramount sends an X12 159 confirming that the latest action film will play on eight screens across three Cineplex locations in Toronto, New York, and Los Angeles. For each theater location identified in the THE segment, Paramount includes the DTP (Date or Time or Period) segment to specify the run dates and booking windows, QTY (Quantity) to indicate the number of prints and showtimes, and optional MEA (Measurements) to detail technical specifications such as aspect ratio and sound format. Within the nested N9 loop, Paramount can attach detailed terms using AMT (Monetary Amount) for revenue splits and PCT (Percent Amounts) for box office percentages specific to each theater, ensuring Cineplex has all confirmed booking terms in a single standardized message.
