Yes, after placing an order, you can change the lot size and UPI ID of your IPO bid.

Please keep in mind that if you approved your UPI mandate request for the order and later modify it, the entire IPO bid amount will be blocked in addition to the amount blocked for your original IPO bid.

In addition, you will receive another UPI mandate request for your revised bid.

However, if you did not approve the original mandate request, no funds will be set aside for the initial IPO bid.
