FIX: A non-variant product is displayed in the cart as Out Of Stock when you add a non-variant product to the cart after you add a variant product in Commerce Server 2007

Consider the following scenario:

• You use a virtual catalog to display products on the Web site in Microsoft Commerce Server 2007.
• You do not directly assign an inventory catalog to the virtual catalog.
• You add a variant product to the cart, and then add a non-variant product to the cart.

In this scenario, the non-variant product is displayed in the cart as Out Of Stock even though there is lots of inventory for that product.

This problem occurs because the stored procedure that is used to perform the inventory check does not reset itself after the first product is added to the shopping cart.
