Hi:
As far as I know, the only way to interface between PowerPoint and SAS is to use the SAS Add-in for Microsoft Office, as part of a SAS Platform for Business Analytics install (also known as the BI Platform).
With the SAS Add-in for Microsoft Office, you can (from within PowerPoint), run SAS tasks and wizards against SAS data sources and return the results to PowerPoint and/or you can run a stored process and return the results of the Stored Process to a PowerPoint presentation.
If you ONLY have SAS Enterprise Guide and SAS; but do NOT have the BI Platform or the SAS Add-in to Microsoft Office, then I believe your choices to create PowerPoint output from SAS are as described in these papers:

If you do have the BI Platform and the SAS Add-in for Microsoft Office, then you may want to repost your question in the Enterprise Guide or the Stored Process forums, where more of the BI Platform folks are likely to be reading posts.
