The Product Compatibility Matrix (PCM) went live a few months ago. This is a great tool to quickly search for requirements data for your deployment.
Recently, it's come to our attention that the tool will come back with no results when using the search criteria dropdowns. JMertin has kindly clarified on how to use the search feature of this tool.
After choosing your product at the initial page, ignore the dropdown boxes and only use the checkboxes in the "limit results to" section and the search filter box just above the results section. This will yield the results you're looking for.
If you have any questions or concerns, please feel free to leave a comment or enhancement request on the community.
