• What is the cause and solution for SAP error message KY104 - Report &1 is already assigned to class &2 ?

  The SAP error message KY104 indicates that a report (identified by &1) is already assigned to a class (identified by &2). This typically occurs in the context of SAP Controlling (CO) when you are trying to assign a report to a class that already has that report assigned to it.
