What is Settlement Id on DIS


Hi friends,
My DP has issued me Delivery Instruction Slip (DIS). For on-market transfer there’s a field called settlement id. My broker said it’s not required.

What is this settlement id and is it necessary to be mentioned on the DIS?
Thanks and regards,


@rohit80 Market trade can not be executed without settlement no . settlement no is of the date on which the trade has been executed . like today 27 June 2019 the NSE settlement no is : 2019121 for normal group .
