Invoice Import Error When Same Bank Account Number Exists with Different Account Types

We have identified the root cause of the AP Invoice Import issue.

When a supplier bank account record exists with the following conditions:

• The same bank account number
• Different account types (e.g., Savings / Checking)

AP Invoice Import via FBDI results in validation errors related to payment method and bank account validity.

Since the account type cannot be specified in FBDI, it appears that the system may not be able to correctly determine which bank account record should be used during the import process.

We would appreciate your guidance on any recommended configuration or best practice that minimizes operational burden on users as much as possible.
