• What is the cause and solution for SAP error message KPEP_WL407 - Hierarchy comparison only possible for object type cost object ?

  The SAP error message KPEP_WL407 indicates that a hierarchy comparison is being attempted for an object type that is not supported. Specifically, this error occurs when the system expects a cost object type but receives a different type of object.
  Cause:
  The error typically arises in the context of cost center accounting or internal order management when:
  
  You are trying to compare hierarchies of different object types (e.g., comparing cost centers with internal orders).
  The configuration or selection criteria in your report or transaction is incorrect, leading to the system attempting to process incompatible object types.
  
  Solution:
  To resolve the KPEP_WL407 error, consider the following steps:
  
  
  Check Object Types: Ensure that the objects you are trying to compare are of the same type. For example, if you are comparing cost centers, make sure all selected objects are indeed cost centers.
  
  
  Review Selection Criteria: If you are using a report or transaction that allows for selection criteria, double-check that you have selected the correct object types. Adjust your selection to include only compatible objects.
  
  
  Hierarchy Configuration: If you are working with custom hierarchies, verify that the hierarchy is correctly configured in the system. Ensure that the hierarchy nodes are defined for the correct object types.
  
  
  Transaction Code: If you are using a specific transaction code (like KSB1, KOB1, etc.), ensure that you are using it correctly and that it is intended for the object types you are working with.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction or report you are using to understand the expected object types and configurations.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this error or provide additional guidance on handling hierarchy comparisons.
  
  
  Contact Support: If the issue persists after checking the above points, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
