  The SAP error message CNV_20900147 indicates that there is an issue with the account group mapping for a vendor during a data migration or conversion process. Specifically, it states that the new account group specified for a vendor does not exist in the table T077K, which is used to store account group definitions for vendors.
  Cause:
  
  Missing Account Group: The account group that is being referenced in the mapping does not exist in the system. This could happen if the account group was not created or was deleted.
  Incorrect Mapping: The mapping file or configuration may have incorrect entries, leading to a reference to a non-existent account group.
  Data Migration Issues: During data migration, if the account groups were not properly migrated or if there were changes in the account group structure, this error can occur.
  
  Solution:
  
  
  Check Account Group in T077K:
  
  Go to transaction code SE11 (Data Dictionary) and check the table T077K to see if the account group exists.
  If it does not exist, you will need to create it using transaction code OBD2 (Define Account Groups).
  
  
  
  Verify Mapping Configuration:
  
  Review the mapping configuration or the migration file to ensure that the account group for the vendor is correctly specified.
  Make sure that the account group is valid and corresponds to the correct vendor type.
  
  
  
  Create Missing Account Group:
  
  If the account group is indeed missing, create it in the system. Ensure that all necessary settings and configurations are applied to the new account group.
  
  
  
  Consult Documentation:
  
  If you are using a specific migration tool (like SAP S/4HANA Migration Cockpit), refer to the documentation for any specific requirements or steps related to account group mapping.
  
  
  
  Test Migration:
  
  After making the necessary changes, re-run the migration process to see if the error persists.
