When the availability of a bundle is calculated it means that all the products that are part of the bundle become part of the output of GetProductAvailability. If this option is turned on, the service will also return information about the bundle to make sense of those extra products.
Determines how bundle availability is calculated. By default the bundle is said to be available when all required lines of the bundle have at least one option that has stock. The alternative is that the bundle is only considered available when the default product for each line has stock.
If not provided then the value of the
ProductBundleAvailabilityCalculationMethodEVA setting is used.
