Remarks
The component provides real time inventory stock checks on items in the customer's basket.
When UpdateInventory fails, such as when the component is unable to decrement the inventory for a line item, UpdateInventory performs the following steps: it writes a generic error, returns an error level of 2, and does not return an HRESULT. The level 2 error prevents the pipeline components after the UpdateInventory component (in the CHECKOUT pipeline) from executing. However, the Orders runtime system does not throw an exception.
Because no exception is thrown, you must write your site code to look through the _Purchase_Errors collections to determine that the pipeline failed to execute completely. Additionally, to determine the line item that caused the error, your site code must check the LineItemCollection and access the indexer property "_inventory_condition" for each line item.
