• What is the cause and solution for SAP error message MDG_BS_BP026 - Several bank keys found for IBAN ?

  The SAP error message MDG_BS_BP026 indicates that there are multiple bank keys associated with a given International Bank Account Number (IBAN) in the Master Data Governance (MDG) system. This situation typically arises when the system finds more than one bank key that corresponds to the same IBAN, which can lead to ambiguity in processing transactions or managing bank data.
  Cause:
  
  Duplicate Entries: There may be multiple entries in the bank master data for the same IBAN, possibly due to data migration issues or manual entry errors.
  Incorrect Configuration: The system may not be configured correctly to handle IBANs, leading to multiple bank keys being associated with a single IBAN.
  Data Inconsistency: There could be inconsistencies in the data across different systems or modules that are integrated with MDG.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Identify Duplicate Bank Keys:
  
  Use transaction codes like SE16N or SE11 to check the bank master data table (e.g., BNKA) for entries with the same IBAN.
  Look for the bank keys associated with the IBAN in question.
  
  
  
  Data Cleanup:
  
  If duplicates are found, determine which entries are valid and which can be deleted or merged.
  Ensure that the correct bank key is retained and that any obsolete or incorrect entries are removed.
  
  
  
  Update Configuration:
  
  Review the configuration settings related to bank data management in MDG to ensure that it is set up to handle IBANs correctly.
  If necessary, consult with your SAP Basis or functional team to adjust the settings.
  
  
  
  Data Validation:
  
  Implement data validation rules to prevent the entry of duplicate bank keys for the same IBAN in the future.
  Consider using data governance processes to maintain data integrity.
  
  
  
  Testing:
  
  After making changes, test the system to ensure that the error no longer occurs and that the bank data is functioning as expected.
  
  
  
  Related Information:
  
  IBAN Structure: Understand the structure of IBANs and how they relate to bank keys in your region.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or solutions for this error.
  MDG Configuration: Familiarize yourself with the configuration settings in MDG related to bank data management, as this can help prevent similar issues in the future.
  User Training: Ensure that users entering bank data are trained on the importance of maintaining unique IBANs and bank keys to avoid duplication.
