Preconditions for Calling the ValidQuote Method
This method is invoked in the eSales - Checkout Process workflow. The sequence called is OrderQuote (see OrderQuote Method), then ValidQuote, and then RemoveInvalidItems (see RemoveInvalidItems Method).
This method checks only the Base Price field in the Quote Item business component. If this field is empty for a record, then the record is invalid. You can override this method to do your own validity checking.
