FIX: You cannot retrieve the latest inventory data by using Commerce Server APIs for the Inventory System in Commerce Server 2007

Consider the following scenario:

• You have a computer that is running Microsoft Commerce Server 2007.
• You enable caching in the Catalog System.
  
  Note You can enable caching by setting the CacheEnabled property on the CacheConfiguration object to True.
• You retrieve inventory data by using the Commerce Server APIs for the inventory system.

In this scenario, you find that the inventory data is not the latest data.

For example, you use the InventoryCatalog.GetSku method to obtain an InventorySku object. The data in the InventorySku object differs from the data in the InventorySkus table. You use the InventorySku.Refresh method to update the object. However, the data is still not updated.

This problem occurs because the inventory data is part of the CatalogItem object. When you enable catalog caching in the Catalog System, the inventory data is cached as part of the CatalogItem object in the product catalog cache. You cannot update inventory data separately.

This hotfix changes the way inventory data is retrieved. When you call the inventory objects to obtain the inventory data, the data is retrieved directly from the inventory system database tables.
