Indian Railway Catering & Tourism Corporation [IRCTC] — Booking history

Address: Nellore, Andhra Pradesh, 524002

Website: irctc.co.in

I have an account in IRCTC and I have booked so many tickets. I want to see my transactions. But it is asking for details like PNR, transaction id, date.
If I have all those details I don't have to use that site for that purpose. I can get transaction details and date from my online banking. But how can I get the PNR number. I request consumer forum to make IRCTC to provide booking transaction history for user without asking those unnecessary questions.
