EDI partner cannot be determined - several bank state. recipients exist

What causes this issue?

The EDI partner cannot be determined, as several bank statement
recipients are defined for bank area & and account number &. Only one
bank statement recipient per account is allowed for dispatching the
bank statements via IDOC FINSTA01. If no bank statement recipient is
defined, the account holder is used as EDI partner.
