Settings for order type in planned orders

Dear All,

Where can i customise the order types for planned order.?

My scenario is.. i can not send complete product in vehicle , which has to be dismantle and send in different vehicle, so the different invoices are required. i can dismantle the product and add these assemblies as line item and invoice. in this case i will loose the main product code which i dont want. i wanted this to behave similar to phantom item , where i can see the phantom item and plan only components.

Please throw sme lite on this...

Thanks

Raghu
