Clearing contact and response history

You might want to clear contact or response history records if, for example, a production run was executed by mistake, or if, after a production run, you decide to cancel the campaign.

Clearing contact and response history permanently deletes this data from the database. Cleared contact and response history cannot be recovered. If later recovery might be required, back up the system table database prior to clearing any history.

Referential integrity across all Campaign system tables is always preserved. All contact history tables are written to simultaneously, and any clean up of contact history is also done simultaneously across all contact history tables. For example, treatment table entries cannot be deleted if there entries in the base or detailed contact history tables referencing them.

You can clear contact history only if you have the appropriate permissions to do so, and if there are no associated response history records. Therefore, if you clear contact history you must also clear the associated response history.

In typical situations, it is best not to delete contact history for which responses have been recorded. However, if you must delete such contact history, you can choose to clear all associated contact and response history records, or clear only the response history records.
