Explanation:
Have you ever asked your Microsoft account team to help you understand what licenses you own? If so, you may have received a spreadsheet listing the contents of your current Select or Enterprise Agreement.
While that information is useful, it's not complete. It only includes data on what you have bought during the current agreement term. What about the products you bought four years ago? Or ten years ago?
To achieve a complete view of your Microsoft investment, you need an inventory - something called a Microsoft License Statement (MLS). This little known spreadsheet document is a comprehensive effort by Microsoft to inventory every license transaction made by your company. It's common to see transactions going back fifteen or twenty years on the MLS.
