Hi everyone,
Our SAM team needs to find the historical installation dates of software to validate against older vendor invoices (e.g., verifying if a user installed an app in 2024 vs 2026). The install_date field is mostly empty since discovery tools (like Tanium) don’t pull historical registry dates out of the box.
I initially suggested using the sys_created_on (Created) date on the cmdb_sam_sw_install table. However, we found this is unreliable because if an endpoint drops off the network or misses a scan, ServiceNow deletes the install record. When the machine is scanned again later, it creates a brand new record, resetting the Created date to “today.”
Since we can’t rely on install_date or sys_created_on , what fields or data points are you using to accurately compare installed software against historical invoice dates? Are there any out-of-the-box ServiceNow fields we might be overlooking for this use case?
