Hi,
Although you can execute Stored Processes from within the SAS Info Delivery Portal, this would not be the right place to ask your question. Short of reading the Platform Administration guide to find out whether it's even possible to integrate IDP with SharePoint, your quickest answer to this question will come from Tech Support.
I suspect, since Microsoft SharePoint is Microsoft Technology and IDP is Java technology, that there may be a few issues in integrating the two differing platforms.
