  The SAP error message SCLT401: "You already have an active trace." typically occurs when a user attempts to start a trace in the SAP system while there is already an active trace session for the same user. This can happen in various scenarios, such as when using transaction codes for performance analysis or debugging.

  Active Trace Session: The user has already initiated a trace session, and the system does not allow multiple active traces for the same user.
