Drafting Principles for new B2b Procedures The content of each procedure will reflect the subject matter of that procedure and not be replicated Redundant or anachronistic material either redrafted or deleted Procedures will be consolidated where appropriate Other changes based on the drafting principles are intended to rationalise, not change the substance of the obligations or rights of the parties to which the procedures apply

Technical specification Questions Schema change: Will there be a mandatory schema change 1st December 2017? Transactional interactions between participants and the B2B/SMP hub: Will participants be able to use their current/preferred method of transacting with the hub? Will the hub transform messages into the preferred transactional method for each participant? Will there be instantaneous transactions? ITWG Commencement When will the ITWG for the SMP commence?
