Create Dynamic Attributes
A dynamic attribute is an attribute whose value is calculated through a formula you create, allowing you to create weighted blends of different attributes to use when sorting.
For example, if you want to create a result set where new products and best selling products are pushed to the top, you can create a dynamic attribute that blends Days Available and Sales Velocity.
Because dynamic attributes are calculated, they can only be numeric, such as integer or number. Date, string, boolean, and set-of value attribute types are not supported. For example, if you add a new sorting rule that is Boolean in
it is not selectable in .Dynamic attributes are referenced by sorting rules, not defined for them; therefore, when a rule containing a dynamic attribute is copied and the dynamic attribute is changed, the changes to the dynamic attribute affect both the original rule and the copy.
