We have items with Income Account A and ARM setup. They were used in sales orders that are not yet fulfilled or billed. Revenue arrangements were already generated. We realized that the income account used was wrong then updated the item record. We deleted the revenue arrangements. The revenue elements were not deleted and bear the OLD income account. We updated the revenue arrangements anyway. The new ones are still using the OLD income account (probably due to the old revenue element that was not deleted). Is there a way to update the income account in the revenue arrangements without re-entering the items?
