Decide what the inventory is for
Support, security, finance and recovery need different fields. Keep the core record small enough to maintain.

Directory accounts, virtual machines, monitoring and purchasing records each reveal assets the others miss.
Turn differences into a process
Assign missing owners, retire stale records and make project handover update the inventory by default.
Official technical sources
These sources support the technical explanation. The right fix still depends on the environment where the problem appears.
