Detect conflicts manually and review conflict details

You can run conflict detection manually for a change request and cancel conflict detection before it completes. You can review the conflicts detected either automatically or manually.

Before you begin

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

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

Prior to running conflict detection, you must consider the following scenarios unique to your organization.
CMDB list size and relationship complexities
If you are 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 switched off by default
When you upgrade, advanced mode conflict checking is switched off by default. Hence, affected CIs are not considered during conflict detection. To evaluate all the CIs, set the mode to Advanced.
