Will this offer also discount your net rate and if so by how much, possible values are:
NONE
The net rate will stay the same, so you will pay for the discount out of your commission. It only affects the retail rate.
FULL
The offer discount will be deducted from the net rate and you'll receive your full commission as if you had sold the booking at full price.
SPLIT
The discount amount will be split 50/50 between you and the supplier. If the discount amount was $10 then the net rate will be reduced by $5.
PRO_RATA
The discount amount will be split proportionally between you and the supplier. So if the booking retail was $50, net rate was $40 and discount was $5, then the net rate would be reduced by $4.
