They rent the vehicle. their business practice is like that if the vehicles are more than 3 years old they sell to iobjects through auction(accept quotation vrom n number of customers for the vehicles) and which ever is highest they sell to that customer. In this situation which transaction type we can use. Because in sales quotation and order object is not used and how to handle pricing for object.
