  The SAP error message CNV_20200_CHECK251 typically occurs during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is an issue with the house bank IDs in the source data, specifically that not all source house bank IDs exist in the target system.
  Cause:
  
  Missing House Bank IDs: The error suggests that some house bank IDs present in the source data do not have corresponding entries in the target system.
  Data Inconsistency: There may be inconsistencies in the data being migrated, such as incorrect mappings or missing configurations.
  Configuration Issues: The target system may not be properly configured to recognize the house bank IDs from the source system.
  
  Solution:
  
  
  Verify House Bank IDs: Check the list of house bank IDs in the source system and ensure that they are all defined in the target system. You can do this by:
  
  Navigating to the relevant configuration settings in the target system (e.g., transaction code FI12 for house banks).
  Comparing the house bank IDs from the source and target systems.
  
  
  
  Create Missing House Banks: If you find that some house bank IDs are missing in the target system, you will need to create them. This can be done by:
  
  Using the transaction code FI12 to create new house bank entries in the target system.
  Ensuring that all relevant details (such as bank key, bank account number, etc.) are correctly filled out.
  
  
  
  Data Mapping: Ensure that the data mapping between the source and target systems is correctly set up. This may involve:
  
  Reviewing the migration mapping settings in the Migration Cockpit.
