iViews for R/3 MM module

I'm looking for iViews on R/3 Materials Management modules - Purchasing, Inventory Management and Vendor Analysis.

Will there be an iView for each transaction code ? or some of the T.codes combined to one iView based on the functionality. Please let me know the list of available iViews for the Materials Management module. I looked at some of the iVews under Business Packages for specialists and these are not related to what I'm looking for (Purchasing and Inventory management). I'll appreciate if some one can guide me on this issue.
