We've installed the Ariba Integration Tool Kit (ITK) which is an Ariba data transfer tool to pull in contract data from our OnDemand solution into our electronic data warehouse (EDW) for use in our internal reporting tool. My memory is not the best, so you'll need to double check this fact of the ITK will pull over event data such as eRFx into your internal system. There is also a 2nd solution titled Web Services. We evaluated both and went with the ITK as it best meet our needs.
Monica, what specific data are you wanting to export from the RFx's?
