Book the chosen free assets for a requisition line still waiting for some, and close the line and its request when nothing is left to book. The booking takes the requisition’s terms unless others are given — kind, who it is for, site, window on the site’s clock, who pays, title and purpose. One that differs from its request needs a reason, and the difference is recorded on the booking and the requisition. Returns the booking.
