We use a custom view for our Owner Statements that shows the different fees paid for each booking in the Bookings section (top part of the statement). We tried to add Credit Card Fees to this view, but the Credit Card Fee values don't populate (see screenshot). The do correctly populate in the Expense section of the report. I believe this is because it's an "Expense Category" and not a "Booking Category". We'd like to request the ability to add fields from the Expense Categories to the Booking section of the Owner Statement. Thanks for the consideration.
If you scroll down more in that drop-down for the Bookings columns, you'll see that there are Expense Categories as well as Surcharge Categories. As you noted, the Expense Categories for CC and Channel fees are there.
