creating purchase orders in admin for OSC 2.3.4

[razgre]

Have you any one worked to create a purchase order which is drop shipped to the customer order to supplier??

 

I would like the ability to go into admin, select an order and print a custom purchase order with a dropdown select for the supplier. The rest of the data would be from OSC, except for my wholesale prices which must go on the PO. I therefore would need to modify my tables to contain these product prices as well as a new table for the suppliers.

 

Any Idea?
