Process for Physical Delivery in F&O

When will I come to know my actual obligation of shares/ funds required for positions which I have placed request for Physical delivery?

The actual Physical Delivery will happen basis the final file received from exchange after the expiry and in case there are shortage of shares in your account at EOD basis the final settlement file then there would be auction for the shortage of shares and such auction charges will be passed on to you and customers will be required to bear such charges form their account. In case of shortage of funds in your account basis of final settlement file the same will be recovered from your account.
