• What is the cause and solution for SAP error message CNV_MBT_DEMO056 - Currency &1 does exist ?

  The SAP error message CNV_MBT_DEMO056, which states "Currency &1 does exist," typically occurs during data migration or conversion processes, particularly when using the SAP Migration Tool or similar tools. This error indicates that the currency specified in the process already exists in the system, which may lead to conflicts or issues during the migration.
  Cause:
  
  Duplicate Currency Entry: The currency you are trying to create or migrate already exists in the system.
  Incorrect Data Mapping: The data being migrated may have incorrect mappings or references to currencies that are already defined in the target system.
  Configuration Issues: There may be configuration settings in the SAP system that are causing the migration tool to misinterpret the existing currencies.
  
  Solution:
  
  
  Check Existing Currencies: Verify the list of currencies in the target SAP system to confirm that the currency in question already exists. You can do this by navigating to the relevant transaction (e.g., OB08 for currency settings).
  
  
  Adjust Migration Data: If the currency already exists, you may need to adjust your migration data to avoid attempting to create a currency that is already present. This could involve:
  
  Removing the currency from the migration file.
  Updating the migration file to reference the existing currency instead of trying to create a new one.
  
  
  
  Review Mapping Configuration: Ensure that the mapping configuration in your migration tool is set up correctly. This includes checking that the source and target currencies are correctly aligned.
  
  
  Consult Documentation: Refer to the SAP documentation or notes related to the migration tool you are using. There may be specific guidelines or known issues related to currency handling.
  
  
  Testing: After making adjustments, perform a test migration to ensure that the error does not occur again.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OB08 (Maintain Currencies) to manage currency settings.
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional guidance on handling currency-related issues during migration.
