Forward Contract Rate

Dear All,

We have a scenario where the USD rate is fixed with a customer for a specific period and/or target sales volume.

For ex - USD @ 33.44 for 3 months or USD 15M

Therefore, every transaction from now on for this customer should use a 'Forward Contract Rate' of 33.44 for 3 months / Sales volume of USD 15M (whichever case is first)

How to implement this ?

Cheers,

Gautam
