At least one transaction/ scheduled transaction is still referenced by a payee. Currently you have all payees selected. However, at least one payee must remain so that the transaction/ scheduled transaction can be reassigned.
Aínda hai un beneficiario que fai referencia dun asento/ planificación. Na actualidade ten escollidos a todos os beneficiarios, pero debe ficar polo menos un para poder asignar de novo os asentos/ planificacións.
