  The SAP error message KY346, "An exception already exists for this area of validity," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with cost center accounting or internal orders. This error indicates that there is an attempt to create or modify an exception for a cost center or internal order that already has an existing exception defined for the same area of validity.
  Cause:
  The error is usually caused by one of the following reasons:

  To resolve the KY346 error, you can take the following steps:
