• What is the cause and solution for SAP error message FV005 - Bank account number not unique ?

  The SAP error message FV005, which states "Bank account number not unique," typically occurs when there is an attempt to process a transaction involving a bank account number that is not unique within the system. This can happen in various contexts, such as when creating or modifying vendor or customer master records, or when processing payments.
  Cause:
  
  Duplicate Bank Account Numbers: The most common cause of this error is that the bank account number you are trying to use is already associated with another entity (e.g., another vendor or customer) in the SAP system.
  Incorrect Configuration: The system may be configured to require unique bank account numbers across certain entities, leading to conflicts if the same number is used.
  Data Migration Issues: If data has been migrated from another system, there may be duplicates that were not cleaned up.
  
  Solution:
  
  
  Check for Duplicates:
  
  Use transaction codes like SE16N or SE11 to access the relevant database tables (e.g., LFBK for vendor bank details or KNBK for customer bank details) and search for the bank account number in question to see if it already exists.
  
  
  
  Modify the Bank Account:
  
  If you find that the bank account number is indeed duplicated, you will need to either change the bank account number for one of the entities or remove the duplicate entry if it is not needed.
  
  
  
  Review Configuration:
  
  Check the configuration settings in the SAP system to see if there are specific rules regarding bank account uniqueness. This can be done in the Financial Accounting (FI) module settings.
  
  
  
  Data Cleanup:
  
  If the issue arose from data migration, consider performing a data cleanup to ensure that all bank account numbers are unique and properly assigned.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for any specific guidelines or best practices related to bank account management.
