Deleting CIs from a dataset by using the Delete activity

As a Configuration Manager, you can delete CIs and relationships from one or more datasets by using the Delete activity. The Delete activity is similar to the Purge activity. For information about the Purge activity, see Purging-soft-deleted-data-by-using-the-Reconciliation-Engine.

Example

Calbro services wants to permanently delete the CIs in a dataset where the attribute AccountID is $NULL$. They trust that they do not need these CIs, hence they do not use the MarkAsDelete attribute to mark each of these CIs for soft-delete. Instead, they create a Delete activity and permanently delete all CIs that match the specified qualification.

Warning

The Delete activity performs a physical delete, not a soft delete, and deletes CIs regardless of whether they are soft deleted.
