It’s the Sample code of Discarding FinancialForce Invoices through API .
While this isn’t an official Mass Discard API, we have got this to work. It is essentially discarding one at a time but in a batch method
public class InvoiceDiscardHelper implements IBatch

this.statefulMessages.get(‘General’).add(‘FinancialForce Invoice Discard’ );
this.statefulMessages.get(‘General’).add(‘——————————‘ );
this.statefulMessages.get(‘General’).add(‘Start Timestamp: ‘ + System.now() );
}

String query = ‘ Select Id, Name From ‘+ invoiceObject +’ Where Id IN :filter’;
return Database.getQueryLocator( query );
