Hi, i have 5 sales orders by week, with the same 10 products. Im doing only one invoice but i need to group all the lines with the same products. Because the invoice shows 50 lines and i wanna show only 10.

Excemple

Order 1: ProductA x 10  and productB x 5

Order 2: ProductA x 5 and productB x 3

Invoice:

ProductA x 15 and ProductB x 8

Can somebody help me with this?

Thanks
