Problem
How do you setup Hourly Rentals for WebTrac in 3.1? It appears the system provides an option for Daily Rentals only.
Solution
If you hide the Nights field on the Rental search screen on WebTrac and set the FieldValue to 0 by default, the system will allow you to do Hourly Rentals. Just select the Date and Begin/End Times.
You can hide the 'Nights' field in WebTrac Management Screen Management. Base Screen Name = WebTrac Rental Search. Expand RNWebSearch_Tab1 Rental Search Criteria (Group).
