It seems like getDocument() must be provided by classes using this trait. How about adding it as abstract method to this trait?

            new DataBaseWhere('iddoc1', $this->idfactura),
            new DataBaseWhere('idlinea1', $this->idlinea)
        ];
        foreach ($docTransformation->all($whereTrans, [], 0, 0) as $docTrans) {
            $quantity += abs($docTrans->cantidad);
        }

        return $quantity;
    }
}
