Hi everyone. We have the need of changing the exchange rate for a specific revenue arrangement line since the customer would love the plan be calculated from the date of the event (fulfillment). Since I think this is not possible, have you ever found a solution / is there an official pattern to do so? I was thinking about projects and milestones for example. Otherwise the only thing I have in mind is to create different sales orders and then group the invoices into 1. Any other idea?
