Interface to create Purchase Order in Ariba

Hi all,

I am new to Ariba and trying to integrate my procurement solution with an Ariba implementation.

The flow I am looking for, is a little different from the general recommended flow. In our case,

- the approval of the items in the cart is in the procurement solution (not Ariba).

- once approved, the order will be transfered to Ariba. This will create a PO in Ariba and pass the Ariba PO number number back to the procurement solution for reference.

I am trying to find out how I can achieve that.

How can I send a Punchout Request to Ariba, to automatically create a PO and pass back the PO number? Is it possible?

Any help will be greatly appreciated.

Thanks !
