Comprehensive and Detailed 150 to 250 words of Explanation From Workday Record-to-Report/Course Guide/topics:

A custom worktag is appropriate because Event Type is required only as a reporting dimension and does not need organizational members, hierarchy behavior, role assignments, or organization-based security. Enabling a custom worktag type and creating values for each event gives users a lightweight dimension that can be placed on transactions, journal lines, reports, and calculated fields.

A custom organization would introduce unnecessary structural and security capabilities that the requirement explicitly excludes. Maintain Worktag Usage determines whether an already configured worktag type is available or required on a transaction type; it does not create the Event Type dimension or its values. Maintain Related Worktag Usage establishes defaulting or required relationships between a business object and another worktag, such as deriving Region from Cost Center. That task also does not create the requested reporting classification. After enabling the custom worktag, the administrator may use Maintain Worktag Usage to expose it on the relevant customer or financial transactions and may add custom validations if the requirement is conditional. The primary design decision, however, is to model Event Type as a custom worktag. This provides precise reporting without overengineering the FDM with an organization that has no organizational behavior.
