Our company uses the newer version of the sponsorship module which includes access to the pilot "trade items" section. In this section, we can list all assets which are considered trade items as a part of the deal sheet (i.e., the client provides us with a specific amount of assets in return for our sponsorship). The sum of this trade item amount should match exactly with the barter amount on the revenue tab of the deal sheet. However, right now the two are independent of each other. We need a way to make sure these two items (the sum of the trade items and the barter amount) are exactly the same without all the manual work.
