If you are working with JetPatch and already triggered many Remediation Plans you can configure automatic deletion.
You will be able to delete the remediation plan if and only if it was cancelled.
Configure automatic Remediation Plan deletion:
1. SSH to JetPatch Server
2. Stop Tomcat service
service tomcat stop
3. Edit the intigua.properties file :
4. Add the following configuration
# JetPatch will delete Remediation Plans automatically X days after the cancellation time
# Default value is 365 days
5. Save file
6. Start tomcat
service tomcat start
