I logged into your polyOne-T account and noticed that you are not integrated yet. In order to make the link from Upstream Contracts Pro to Downstream P2P your realms will need to be integrated. Once they are integrated you can make the link from your contract workspace via the documents tab. By clicking on the documents tab you will see an option after clicking the action button titled, "Contract Terms". When you select this option the system will navigate you through the screens you are familiar with in P2P.
I am not sure of the details on how you will be deploying Contract’s Pro, but Ariba typically integrates during the deployment. This cannot be done right way since there are some technical implications that need to be reviewed by both Ariba and PolyOne.
Hope that helps,
A bit late in responding, but this is definlty something that you would want to see in action first, and then build a plan around. When working in an integrated enviornment, the two objects, the ACW workpace and the ACC Contract Request-Contract are directly linked and share some common elements such as "effective and Expriation Dates" and common supplier. You can not have a Draft Compliance Contract and a Published ACW workspace so to say that are linked. To amend one automatically amends the other. A demonstration would be the first step I'd recomend.
