How to create test B2B invoice in OBN

Summary:

Hi All,

We have a requirement to test some attributes in a B2B invoice sent from OBN. Currently, to test these invoices, we have to ask suppliers to submit some invoices from their Test a/c to our test OBN account.

I want to know is there a way to create these test invoices in OBN Test account, without asking or waiting for suppliers everytime for testing purpose?
is there any webservice available?

Thank you,

Rajat
