PassengerDetailsRQ for round trip

Question

We're working on integration of API in our system.We had done pretty well for the one way trip and generate PNR successfully but we are stock on the PassengerDetailsRQ for round trip. I am sure BargainFinderMaxRQ is correct for round trip but we are confused on EnhancedAirBookRQ too . So , I am attaching both EnhancedAirBookRQ and PassengerDetailsRQ for round trip here. Hope some help from sabre.

EnhancedAirBookRQ :

Answer 1

MiscSegment is not required to complete a PNR, but an itinerary is.

Are you not making the EnhancedAirBook call first,(to book the flights and include them in the itinerary) and then (using the same BinarySecurityToken) calling PassengerDetails? BTW, the call to PassengerDetails does not need to know whether your itinerary is round trip or one way...
