Summary:
Customers may encounter an error after the supplier import file is generated in Basware, as the supplier IBAN details in Basware P2P Admin are not updating due to uniqueness constraints.
System Behavior
- IBAN values in Basware P2P Admin must be unique for the same supplier.
- If an IBAN already exists in the system for the same supplier then system will return the error:
"value already in use"
Example of Submitted Bank Details
xml
<SupplierBankAccount>
<Bban>1234567</Bban>
<Name>002</Name>
<Iban>123456789 </Iban>
<Swift>DEUTDEDWXXX</Swift>
<IsDefault>True</IsDefault>
</SupplierBankAccount>
Reason for Failure
- The IBAN 123456789 is already associated with the supplier, which prevents it from being updated again.

Resolution Steps
- Please verify the IBAN being imported for the supplier from supplier import file.
- Provide a new, unique IBAN that is not already in use in the system for the same supplier.
- Once a unique IBAN is provided, the update can be processed successfully.
