Helen Hammond originally booked 500 gallons. There are 200 gallons remaining.
Helen receives a 400 gallon delivery. She will receive 200 gallons at the booked price and the remaining 200 gallons at List Price. Notice the Level column heading says View instead of Book. This indicates the system needs interaction.
Select View. On the following window that appears, highlight the Booking to use and choose Done.
Select the Split option, then choose OK.
The result is two lines - one line at the booked price, the other line at List Price. This price may be changed if needed.
