My customer has hedge contracts with the bank.
The accounting currency being SEK and their main purchase currency being USD they safeguard themselves against currency rate fluctuations by frequently securing different USD amounts at negotiated rates with their bank. These contracts are for a settled total amount and has an end date. They have overlapping time intervals, a new contract is made before the previous is ended.
The result being that when they pay suppliler invoices they use these different contracts to ensure the best possible rate for every payment. Not a problem, but:
...as the amount on one contract runs out one supplier invoice payment may be based on amounts from two different fixed rate contracts, One part of the payment is at one currency rate and the remaining amount is paid at another rate.
This is a fairly common issue - how do IFS customers usually handle this?
