Add Shippable Items to Purchase Order

Hi Team,

We have a requirement to update the Purchase Order (R 12.1.3) once we have received the Shippable Item List (SIL) from our supplier i.e. we initially raise a PO with only one line say 'DUCT' and finally the supplier gives us the list of items which will finally make the 'DUCT' and now as part of traceability we want to record the receipt of each sub assemply parts so we want to amend the PO with these shippable items once we receive the SIL from our supplier.

Can this be handled by creating a BOM for the item 'DUCT' and does Oracle automatically update the PO or does it automatically ask user to receive the sub assembly during PO receiving process.
