# CostCategoryInheritedValueDimension


When you create or update a cost category, you can define the `CostCategoryRule` rule type as `INHERITED_VALUE`. This rule type adds the flexibility to define a rule that dynamically inherits the cost category value from the dimension value that's defined by `CostCategoryInheritedValueDimension`. For example, suppose that you want to dynamically group costs that are based on the value of a specific tag key. First, choose an inherited value rule type, and then choose the tag dimension and specify the tag key to use.
