Lets say 2 lines were added to Sales order upon creation and revenue arrangement got created both on same day. i.e. 1/1/2020. On 2/1/2020 1 lines was added on sales order which is the same item as on line 1, is it possible to have the revenue arrangement have the source date field to reflect 2/1/2020 for this 3rd line which was added on 2/1/2020. For this 1st line and 3rd line which are same item, we have to separate fair value prices records, for one its start and end date in fair value record are 1/1/2020 and 1/31/2020 and for another record its start date is 2/1/2020 with no end date specified.
