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.
Calbro services wants to permanently delete the CIs in a dataset where the attribute
$NULL$. 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.
The Delete activity performs a physical delete, not a soft delete, and deletes CIs regardless of whether they are soft deleted.
Before you begin
Create a qualification ruleset to specify the instances and classes that are deleted. For creating a qualification ruleset, see Creating qualification rules for reconciliation activities.

Selected - The job continues to run even if an error occurs in this activity.
Cleared - The job is terminated if an error occurs in this activity.
