This feature enables optimizations for the Product availability job used by both Store and Online channels. Before enabling this feature, ensure you have made the necessary changes to your e-Commerce site to leverage the new GetEstimatedAvailabilty and GetEstimatedProductWarehouseAvailability APIs. Selecting the optimized process stops all future data updates in the legacy RetailInventAvailability table. If your organization has customizations which leverage this legacy table, ensure these customizations are refactored prior to enabling this option.
