Hola

Yo estoy de acuerdo con Casimiro, hay que obtener el precio de la última fecha. A ver si esto funciona para lo que deseas.

Código SQL [-]
Select 
   Max(Codclient) as Codclient, 
   Max(Fecha) as Fecha,
   Producto, 
   Sum(Unidades) as Unidades,
   Max(Precio) as Precio, 
   Sum(Subtotal) as Subtotal, 
   Avg(Precio) as PMedio, 
   Min(Precio) as MPrecio,
   (select first 1 X.precio from LineasVentas X where X.Codclient = :C And X.Fecha between :F1 and :F2 order by X.fecha desc) as UltimoP
   
from LineasVentas
Where Codclient = :C And Fecha between :F1 and :F2
Group By Producto
Having Sum(Unidades) <> 0
Order by Producto

Saludos
