CNV_PE185 - Details

• The SAP error message "CNV_PE185 Transformation rule &1 already exists" typically occurs during data migration or transformation processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that a transformation rule with the specified identifier (represented by &1) already exists in the system.
  
  Cause:
  
  
  Duplicate Transformation Rule: The most common cause of this error is that a transformation rule with the same name or identifier has already been created in the system. This can happen if:
  
  The same migration project is being executed multiple times without proper cleanup.
  There was an attempt to create a new transformation rule with an identifier that is already in use.
  
  
  
  Incorrect Configuration: Sometimes, the configuration settings or the mapping of the transformation rules may lead to conflicts, resulting in the creation of duplicate entries.
  
  
  
  Solution:
  
  
  Check Existing Transformation Rules:
  
  Navigate to the relevant transaction or application where transformation rules are managed (e.g., the Migration Cockpit).
