• What is the cause and solution for SAP error message KY085 - Report class and superior report class are identical ?

  The SAP error message KY085, which states "Report class and superior report class are identical," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with report classes in the context of cost center accounting or internal orders.
  Cause:
  This error arises when you attempt to create or modify a report class in such a way that it references itself as its superior report class. In other words, the system detects that the report class you are trying to define is set to be its own parent, which is not allowed. This creates a circular reference that the system cannot process.
  Solution:
  To resolve this error, you need to ensure that the report class you are defining does not point to itself as its superior report class. Here are the steps to correct the issue:
  
  
  Check Report Class Configuration:
  
  Go to the transaction code for maintaining report classes (usually KOB1 or KOB2).
  Locate the report class that is causing the error.
  
  
  
  Modify the Superior Report Class:
  
  Ensure that the "Superior Report Class" field is set to a different report class that is not the same as the current report class.
  If you do not have a superior report class, you can leave this field blank or set it to a valid existing report class.
  
  
  
  Save Changes:
  
  After making the necessary changes, save the configuration.
  
  
  
  Test the Configuration:
  
  After saving, try to execute the report or transaction again to ensure that the error has been resolved.
