Greetings:
All recordings of available BPC webinar recordings can be accessed at the following link: http://www.ariba.com/help/ariba-answers/buyers/drive-optimal-results-from-your-ariba-solutions?campaigncode=CRM-XI14-XAM-CM_BPCCOM&t=1
If the topic or recording you are seeking is not listed, then it is not available.
You can request a webinar topic for the Best Practices Center team (BPC) to add to an upcoming live webinar, or you can work with your Ariba account contact to purchase BPC hours so that that the topic can be delivered personally to your team.
Regards,
Debbie Curtis-Magley
