Run conflict detection manually for a change request and cancel conflict detection before it completes. Review the conflicts detected either automatically or manually and resolve them by changing the schedules.

Before you begin

Before you can run conflict detection for a change request, the following fields must be completed in the change record.
  • Configuration item, except in advanced mode. In advanced mode, the Affected CIs field is required instead.
  • Planned start date of the change request.
  • Planned end date of the change request.

For more information about running conflict detection automatically, see Enable automatic change conflict detection.

Prior to running conflict detection, consider the following scenarios unique to your organization.
CMDB list size and relationship complexities
If you have a large organization with a large CMDB, conflict detection can take longer to complete.
Inactive changes are not evaluated
Conflict detection does not evaluate inactive changes when determining conflicting changes.
Advanced mode conflict checking is disabled by default
When you upgrade the application, advanced mode conflict checking is disabled by default and affected CIs are not considered during conflict detection. To evaluate all the CIs, set the mode to Advanced.
