Deleting an Inventory Record
FlexNet Manager Suite 2019 R2 (On-Premises Edition)   
        You can delete an inventory record when it is no longer required in the system. You
                may delete a record if you find duplicate or erroneous inventory records.
        Note: Deleting a record updates the database
                    immediately, as expected. However, if FlexNet Manager Suite is in
                    'high-frequency mode' (or 'PVU mode', responsible for sub-capacity points
                    calculations in place of ILMT) and the inventory device is consuming from
                    any IBM PVU licenses, the device record is not actually deleted straight away
                    (and a different database update is performed instead, as follows). This is
                    because IBM PVU licenses require retrospective calculation of consumption points
                    for the entire reporting period (and this calculation is reworked from scratch
                    as part of the nightly full compliance calculation), so that removing the device
                    record while it should still influence those retrospective calculations would
                    introduce an audit risk. Therefore, instead of being deleted immediately,
                    devices still required for those calculations are given an
                        Archived status (and immediately moved to the
                        Archived Inventory page). An
                        Archived device acts just like a deleted one in
                    every way except its continued availability for retroactive corrections
                    and retrospective calculations. Archived devices
                    are automatically deleted once they can no longer affect consumption in the data
                    retention period.
