Which field is used to create a milestone step on a milestone path in the Setup area?

A milestone step within a Milestone Path represents a specific system status. When a system administrator creates a new project status in the Adobe Workfront Setup area, the "Key" is a mandatory and unique field. This key serves as the system's internal, immutable identifier for that status. While a user might select a status by its name in the user interface when building the milestone path, the underlying "Key" is the fundamental field that uniquely defines the status object, enabling its creation and subsequent use as a milestone step.

A. Status: This term is too general. A milestone step is a status, but "Key" is the specific, unique identifier field required to create the status object in the system's backend.
B. Description: This field is used for providing optional, supplementary text about the status or milestone. It is not a required or identifying field for its creation.

1. Adobe Workfront Documentation, "Create and edit statuses": This document explicitly details the fields required to create a new status. It states, "Key: This is a required field. The key is used to identify the status in the database. The key is not visible in the user interface to all users... We recommend that you use a key that is relevant to the name of the status." This confirms the "Key" is the fundamental identifier for the status object. (Adobe Experience League, Workfront Documentation, Setup > Project Preferences > Statuses section).

2. Adobe Workfront Documentation, "Create a milestone path": This guide explains that a milestone path is a sequence of system statuses. It notes, "A milestone path is a series of statuses that a project goes through from start to finish." When adding a milestone, you select a "System Status." This establishes that the milestone step is a direct application of a status object, which is fundamentally defined by its "Key" as per the first reference.
