Problema con Consulta SQL

Hola, no se que quiere decir que no sume, pero te hago un comentario, si
tenes valores nulos vas a estar en problemas, yo te recomendaria entonces

SELECT
InvoiceHeader.season,
InvoiceHeader.N_Invoice,
InvoiceHeader.Type,
InvoiceDetail.PlantName,
Sum(isnull(InvoiceDetail.Qty,0)) AS SumaDeQty
FROM InvoiceHeader INNER JOIN InvoiceDetail ON
(InvoiceHeader.N_Invoice = InvoiceDetail.Invoice) AND
(InvoiceHeader.Type = InvoiceDetail.Type)
WHERE (((InvoiceHeader.InvoiceDate) Between @fecha1 And @fecha2 ))
GROUP BY InvoiceDetail.PlantName, InvoiceHeader.season,
InvoiceHeader.N_Invoice, InvoiceHeader.Type;



Saludos
