Values for Event Type and Source/Campaign can be stored against each booking and used for reporting purposes. Here's how to use them......
For Event Type, set your Event List in Operational Parameter 83, you'll then see a drop down list against Event Type in each booking.
For source/Campaign, just enter a value into the field in the booking. RentalPoint will remember the value you used and add it to a drop down list for future use.
