SAP® STORE APP: BUSIENSS PARTNER VALIDATOR XTENSION

The Business Partner Validation Tool helps users verify the correctness of VAT IDs and IBANs for business partners before onboarding or performing financial transactions. The application provides a simple user interface where you can select a VAT ID and/or IBAN from dropdown lists, run validation, and immediately see the results in dedicated result cards. Scope of Validation: 

• VAT validation via EU VIES API 
• IBAN validation via OpenIBAN service 

Key Benefits

• Real-time EU VAT validation via VIES
• Instant IBAN & SWIFT format checks
• 100% SAP BTP-native, no middleware required
• Fast deployment, zero additional cost
• Improved data quality & compliance

Before using the application, make sure: 

• You have access to the corporate network or SAP® BTP® environment 
• Your user account has permission to open the BP Validator App 
• Partner master data contains valid VAT IDs and/or IBANs 

1) Log in to the BP Validator App using your corporate/SAP® credentials. 

2) The main screen shows two dropdown fields: one for VAT IDs and one for IBANs. 

1) Select a VAT ID from the VAT dropdown (optional). 

2) Select an IBAN from the IBAN dropdown (optional). 

3) Click the 'Validate' button. 

4) The results will appear in two separate cards:
   • VAT Result – Shows status (Valid/Invalid/Unknown). If valid, it also displays the registered company name and address (when provided by VIES/VATComply).
   • IBAN Result – Shows status (Valid/Invalid/Unknown). 

• Valid – Green checkmark, data confirmed. 
• Invalid – Red cross, data incorrect or not recognized. 
• Unknown – Grey dash, validation not executed or no decision from the service. 

• Always validate partners before onboarding or initiating financial transactions. 
• If only VAT or IBAN is available, validate them independently. 
• Re-run validation periodically to capture any changes in partner data. 
• Save or export validation results if required for compliance. 

• VAT shows 'Unavailable': VIES may be temporarily down – retry later. 
• IBAN shows 'Unknown': check if the country is supported by OpenIBAN. 
• Ensure VAT IDs and IBANs are formatted correctly (uppercase, no spaces).
