• What is the cause and solution for SAP error message CNV_20400_CHECK090 - Controlling areas being merged into COAr &1 do not use CO templates ?

  The SAP error message CNV_20400_CHECK090 indicates that there is an issue related to the merging of controlling areas in the context of a data migration or conversion process. Specifically, this error occurs when the controlling areas that are being merged into a target controlling area (COAr &1) do not utilize the same CO templates.
  Cause:
  
  Different CO Templates: The controlling areas being merged have different CO templates. CO templates define the structure and configuration of controlling areas, including cost centers, profit centers, and other controlling objects.
  Inconsistent Configuration: The configuration settings for the controlling areas may not be aligned, leading to incompatibility during the merging process.
  Data Migration Issues: This error often arises during data migration or conversion activities, where the system checks for consistency and compatibility of the controlling areas involved.
  
  Solution:
  
  
  Check CO Templates: Verify the CO templates used by the controlling areas that are being merged. Ensure that they are the same or compatible.
  
  You can do this by navigating to the controlling area configuration in SAP and checking the assigned CO template for each controlling area.
  
  
  
  Align Configuration: If the controlling areas are using different templates, you may need to align their configurations. This could involve:
  
  Modifying the configuration of one or more controlling areas to use the same CO template.
  Creating a new CO template that encompasses the necessary configurations for all controlling areas involved.
  
  
  
  Review Migration Settings: If you are using a migration tool or program, review the settings and parameters to ensure that they are correctly configured to handle the merging of controlling areas.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or prerequisites that need to be followed.
  
  
  Testing: After making the necessary adjustments, perform a test run of the merging process to ensure that the error does not reoccur.
