• What is the cause and solution for SAP error message CNV_20400_CHECK031 - All Currencies is active for all controlling areas ?

  The SAP error message CNV_20400_CHECK031 indicates that the "All Currencies" setting is active for all controlling areas in your SAP system. This error typically arises during the migration or conversion process, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error occurs because the system has detected that the "All Currencies" option is enabled for all controlling areas, which can lead to inconsistencies or issues during the data migration process. This setting allows for multiple currencies to be used within the same controlling area, which may not be compatible with the migration requirements or the target system configuration.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Controlling Area Settings:
  
  Go to the transaction code OKKP (Controlling Area: Maintain).
  Review the settings for each controlling area to see if "All Currencies" is activated.
  
  
  
  Deactivate "All Currencies":
  
  If "All Currencies" is active and you do not require it, consider deactivating it. You may need to set a specific currency for each controlling area instead.
  Note that changing this setting may have implications for your financial reporting and data consistency, so ensure that you understand the impact before making changes.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of SAP you are using. There may be specific guidelines or recommendations for handling currency settings during migration.
