The license inventory contains all rights of use for a product version at a specific point in time. The basis of the license inventory is formed by the usage rights of the individual licenses. These rights consist of the total number of licenses and contracts per product version and the regulations on permitted use. These usage rights also include, for example, update and downgrade rights, special usage rights resulting from maintenance agreements or framework agreements (e.g. scope). Licenses that are time-limited and have lost their validity are not counted in the license inventory.
