This error typically arises in the context of financial data migration, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  The error occurs when the same house bank ID is assigned to multiple company codes within the system. In SAP, each house bank must be unique per company code to ensure proper financial transactions and reporting. Duplicate entries can lead to confusion in financial operations and reporting, which is why the system raises this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Duplicate House Bank IDs:

  You can also run a query to find duplicates based on the house bank ID and company code.
  
  
  
  Review Company Code Assignments:
  
  Check the assignments of house banks to company codes. Ensure that each house bank ID is assigned to only one company code.
  If a house bank is mistakenly assigned to multiple company codes, you will need to correct this.
  
  
  
  Modify or Remove Duplicates:
  
  If duplicates are found, decide whether to modify the existing entries or remove the duplicates. You may need to create a new house bank ID for one of the company codes if necessary.
  Ensure that the changes align with your organization's financial structure and reporting requirements.
  
  
  
  Data Migration Preparation:
  
  After resolving the duplicates, re-run the data migration or conversion process to ensure that the error no longer occurs.
