    Cause
    The message WK021 occurs during workflow processing in SAP when a substitution rule has been executed and the substitution process has ended. This message is informational and indicates that the system has completed the substitution of an agent (user) in a workflow step.
    In SAP Workflow, substitution is a mechanism that allows one user to act on behalf of another user, typically when the original user is unavailable (e.g., on leave). The system checks substitution rules to find an alternate agent to process a workflow task.

    A valid substitute user was found and assigned.
    No substitute was found, and the substitution process ended without assignment.
    The substitution rule logic has completed its evaluation.
