• What is the cause and solution for SAP error message KA394 - Row & can not have overhead applied to it through itself ?

  The SAP error message KA394 ("Row & can not have overhead applied to it through itself") typically occurs in the context of cost accounting, particularly when dealing with cost center accounting or internal orders. This error indicates that there is an issue with the way overhead costs are being applied to a specific cost element or cost center.
  Cause:
  The error arises when you attempt to apply overhead costs to a cost element or cost center that is already being used as a source for the overhead calculation. In other words, the system is trying to apply overhead to itself, which creates a circular reference that is not allowed.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Overhead Calculation Settings: Review the overhead calculation settings in the configuration. Ensure that the cost element or cost center is not included in its own overhead calculation.
  
  
  Adjust Cost Element/Cost Center: If the cost element or cost center is indeed being used in its own overhead calculation, you will need to adjust the configuration to prevent this circular reference. This may involve changing the overhead calculation rules or using a different cost element/cost center for the overhead application.
  
  
  Review Allocation Structure: Check the allocation structure to ensure that the cost element or cost center is not inadvertently included in its own overhead calculation.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring overhead calculations and avoiding circular references.
  
  
  Testing: After making changes, perform a test run to ensure that the error does not occur again.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as KSV1 (Create Overhead Key) or KSV2 (Change Overhead Key) to manage overhead settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on overhead calculations.
  User Roles: Ensure that you have the appropriate permissions to make changes to cost accounting settings in SAP.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP Controlling (CO) module for further assistance.
