assign an accounting account to a transfer from ba

I have a problem with Dolibarr 8.02
I could not assign an account when I transfer from bank accounts.
The problem is seen in the financial book (Libro Diario o financiero) with the following error: “Accounting account of unknown third party. Blocking error”
In spanish it would be: “Cuenta de tercero desconocida. Error de bloqueo”
Can somebody help me?
