I am working in a textile company which has production subcontracted in diverse countries and we try to generate the subcontracting purchase orders. Grouping by vendor or date work great but we still miss the possibility to group by item. In our case we have different production orders by item, color and size and the subcontracting purchase orders have lot of identical lines with the same item which does not allow us to set a right purchase price per qty. I mean we have different purchase prices for the service item if for example 10 trousers are produced, another from 50 units and so on. Would be great them to have the possibility to group the purchase order lines by item although it can be tricky for Microsoft to manage the right references to the corresponding production orders.
