Create Multi Line Requisitions

Hello Gurus.

We have been live on 12.1.3 since April 2017.

Our business is now seeing the need to upload multi Line Requisitions.

These could be 100s of lines long. At the moment all we have is User/Keyboard interface.

In my mind I see a product, something like ADI (for GL journals) that could meet our needs. Would this be possible?

Alternatively we may have to write an interface ~ po_requisitions_interface_all?

Or maybe we need to engage and purchase a third Party product?

I had thought about re-introducing  the Copy Requisition function but...

We operate Punchout to a large stationery vendor.
