Hi Rodrigo:
I contacted Bobby Arzola, who is the Ariba customer engagement executive for Zoetis. He provided the following response to your posting:
"It sounds like Zoetis may have started solution confirmation activities for their Brazil deployment. Although On-Premise customers have the ability to make significant customizations, the On-Demand solutions should not be viewed as lacking in functionality. There are Ariba/SAP solutions for many of the business requirements you referenced. Rodrigo, if you have not already done so, I would encourage you to speak with the Zoetis global implementation leads (Gary Cleek and Bruce Reid) as they may be able to provide additional guidance on approved solutions that are in alignment with their global model."
