Unexpected things can happen at any time affecting the product availability, even after the Prebook has been created. Notify the sales person and mark the product as Unable to Source by using this feature. This way your clients can make decisions about getting different products or waiting a little longer for you to find them with a different grower. This mark is available for Prebooks in units and boxes.
This feature can also be used in the Bulk Purchasing Mode and from the Vendor Portal.
