Remarks

Use the RemoveParentCategory method to remove a parent category from this category. If the category specified in the strCategoryName parameter does not exist, then this method will fail.

When calling this method on an inherited category in a virtual catalog, the method will have no effect if the parent-category relationship is inherited from a base catalog. If the relationship was added in the virtual catalog it will be removed. Inherited hierarchy and relationship links cannot be removed or changed in inherited categories. To modify inherited relationships use a Category object obtained from the base Catalog object.
