Hi all,

We have a product "Shaft" that undergoes several Subcontracting processes to use that product in manufacturing process

This shafts undergoes process

 Turning -> Subcontractor-1

 Milling ->  Subcontractor-2

 Drilling -> Subcontractor-3

 Plating ->  Subcontractor-4

For Shaft we have to buy rod from a vendor "A"

We have to supply rod to subcontractor-1 and there it undergoes turning process and converts to turned shaft

Next turned shaft supply to subcontractor-2 and there it undergoes milling process and converts to milled shaft

next milled shaft supply to subcontractor-3 and there it undergoes drilling process and converts to drilled shaft

and finally drilled shaft supply to contractor-4 and it undergoes plating process and converts to shaft
