Error en script de ventas

[tnlgortiz]

Hola a todos, tengo el siguiente script para mostrar las ventas del mes, pero observo que me aparecen unas notas de debito del 2019, es algo raro. ¿Alguien me podria decir que me faltaria para que no carguen esas ND, ya que la consulta es Mayo 2021?

Buenas tardes, esa sentencia OR la deberias utilizar dentro de parentesis ()

@tnlgortiz

MONTH(T0.DocDate) = 5 AND
	T0.CANCELED = 'N' OR
	T0.CANCELED = 'Y' AND
