Availability works for both Class and Class Web options, but has particular relevance to web bookings, where human intervention is not available to make the decision on whether or not a booking can be accepted!

Availability enables the setting of daily/weekly limits for a product group, so for example a "Home Stay" group (which links all the homestay accommodation price items together) could be used to stop overbooking occurring on particular days or weeks.
Similarly, a residence which has finite space could have limits set to prevent overbooking.

The Availability function also allows "minimums" and "maximums" to be set, allowing for the following type of controls:

1. 2 weeks = minimum course booking duration
2. 4 weeks = maximum course booking duration
3. Summer Course - 2 weeks min/4 week max, at start of summer, and 2 week min/4 week max for the last 2 weeks of summer. The min/max values can be adjusted on a day-by-day basis to reflect the options available.

The "Quantity" available can be entered either on a cell-by-cell basis or by using the "Range Update" option.
This sets the availability and may be changed to reflect day-by-day situations.
For example, a residence may have variable availability during the summer period.

Minimum and maximum values can be entered in the same way.

Price Items need to be assigned so Class knows which price items are to be controlled by this function.
In the above example, all Home Stay price items have been selected.

Please note the filters at the top of the screen, particularly "Only List Web Items!, which will restrict the list to only those which have been Web-enabled.

When "OK" is selected, the "Rebuild Totals" function will automatically calculate the current position. Class will then maintain these values automatically.

When viewing the availability, the "Rebuild" option can be run to recheck the totals, although Class will maintain them automatically.
