Currently, requirement from customer at Poland location is to have fixed currency rate on sales contract for having planned revenue at a single rate and to have daily transaction rate on invoice.

For purpose of same, fixed currency rate has been defined in currency rate type which is updated on sales contract and this rate is getting fetched on respective project invoice.

However as per Polish local requirements, the Currency Rate on the invoice it should be daily transaction rate based on delivery date defined in Currency Rate type as TRANS_RATE (daily rates being updated).

As of now, this functionality is included in Polish localization for Tax Currency Rate of invoice only but not for Invoice amount.

Please share best practice to handle this scenario and whether to be part of localization or not.
