Process for Physical Delivery in F&O

What in case if I am e-DIS customer and do not take mandate or mandate proves invalid due to any reason?

If you are e-DIS customer and you do not have a valid e-DIS mandate required for the position you have chosen Physical settlement then such positions may get squared off or if physical delivery obligation is received then may go for Auction and the Auctions charges will be passed on in your account and will need to be borne by you.
