Hi,

Maybe you should do the Peek with -Booking ID:

e.g :

LOAD

          *,

          if(Peek([Booking ID])<>[Booking ID],ECouponAmount,'0') as ECouponAmountFinal;

LOAD * INLINE [

    Booking ID, Approval Code, Transaction Date, Collection Amount, ECouponAmount

    NF2101322199095, , 08/10/2012, 1634, 100

    NF2101322199095, , 03/11/2012, 249, 100

    NF2101322199095, BYPASS, 04/10/2012, 0, 100

    NF2101322199095, 19233, 08/10/2012, 975, 100

You may need to relad the table first, with an Order By clause, to make sure it is in the expected order.
