grant permission to SHOW FIELDS

I create a user to make a dump twice a week but when I try to execute mysqldump I have this error mysqldump: Couldn't execute 'SHOW FIELDS FROM contabilidad_amortizaciones_completas_por_id_vista': execute command denied to user 'dump'@'%' for routine 'bbbdd57_antes_del_cambio.calcula_dotacion_acumulada_fc' (1370) The grants to this user are these GRANT SELECT, SHOW DATABASES, LOCK TABLES, EVENT ON *.* TO 'dump'@'%' The function call 'bbbdd57_antes_del_cambio.calcula_dotacion_acumulada_fc' have this code: CREATE DEFINER = 'root'@'%' FUNCTION bbbdd57_antes_del_cambio.calcula_dotacion_acumulada_fc(_id_amortizacion int) RETURNS decimal(10,2) BEGIN SET @resultado = 0; ( SELECT SUM(R.acumulado) FROM ( SELECT MAX(cadm.acumulado) AS acumulado, cadm.id_amortizacion FROM contabilidad_amortizaciones_detalles_meses cadm WHERE ((cadm.id_amortizacion = _id_amortizacion) AND (cadm.contabilizado = 1)) GROUP BY cadm.anio_detalle, cadm.contabilizado ) AS R GROUP BY R.id_amortizacion INTO @resultado ); RETURN @resultado; END I have other instances with other users-dump with this permissions and I don't have any problem.
