Remarks
The RemoveRelationshipToProduct method removes a relationship between this category and the product identified by the varRelatedProductID parameter. Since more than one relationship may exist between this category and product, you must also specify the name of the relationship you wish to remove in the strRelationshipName parameter. If the product specified as the varRelatedProductID parameter does not exist or the relationship specified as the strRelationshipName parameter does not exist, then this method will fail.
