Can I Analyze the Reason for a CI Deletion in SM

No.

SM opens a change request on the deleted CI and includes the following information:

“Delete event for CI “CI Name” triggered by discovery”.

Workaround

An SM change request does not contain a description of the reason for deletion, however it is possible to extract specific information about CI deletions from the UCMDB “History Database”. UCMDB data provides information about the user or the discovery pattern that initiated the CI deletion.
