sales order item

mine is a make to order strategy.

so my production is triggered by the sales order.

if my sales order is having two items.

do i know that any where in my production order.

in the production order general screen.

we can see my sales order number and the line item no.

but i want to know how many of that line items are there in my sales order.

because mine is a seed company. so order will be two or three different boxes for one single customer.

so they will club all the three boxes and post them to the customer.
