Select two correct statements about project classifications on a template.

Project classifications are used to group and report on projects based on different criteria. A project template can have one or more project classifications, which can be either required or optional. When a project is created from a template, the required project classifications must be entered, while the optional ones can be left blank. A project class category in a project classification must be associated with a set code, which determines the list of values for the project class. Project classification is not a mandatory field on a project template, but it is recommended to use it for reporting purposes.Reference:https://docs.oracle.com/en/cloud/saas/project-portfolio-management/20c/oapfm/manage-project-plans.html#OAPFM2355961
