Be logged in to the Site Manager;
Know the dynamic attribute(s) you wish to add;
Know if you are adding the dynamic attribute to an existing attribute group, or if you are creating a new attribute group. If you are adding the attribute to an existing attribute group, you will need to know the name of that attribute group. If you are creating a new attribute group, you will need to know the details for that group so that you can create it;
Know which product type to associate your new attribute with. If the product type already exists, you will need to know if the attribute group is already associated with the product type. If the product type does not exist, you will need to know the details of it so that you can create it.
