Inventory device records created in FlexNet Manager Suite 2020 R1 and later for computers imported from an SCCM inventory source are not deleted as expected when:
Associated computer records in the SCCM database are deleted or obsoleted; AND
The connection to the SCCM inventory source is configured on the FlexNet Manager Suite batch server.
This behavior occurs because there is no implemented logic that runs to identify computer records that have been deleted or obsoleted in the SCCM database when then SCCM inventory “readers” process runs on the batch server.
Configure the connection to the SCCM inventory source on a standalone beacon (rather than than on the batch server).
This issue is still open but not currently scheduled to be addressed.
