Details of merging and applying changes

There are two different ways that PolicyCenter copies changes from a previous job into another job.

• Merging changes (OOS) – For an out-of-sequence job, PolicyCenter calculates all out-of-sequence changes that are conflicts. Given these out-of-sequence conflicts, the user can choose to merge those changes in the same branch but at later effective dates in the same policy period. For more information, see Out-of-sequence jobs.
• Applying changes (preemption and future renewals) – PolicyCenter can calculate all differences between two branches A and B, including entity instance adds, removals, and property changes. PolicyCenter can reapply those differences (the “deltas”) to another branch C to recreate what changed between A and B. This occurs as part of handling preemption and processing changes to policies if there is a future renewal. For more information, see Preempted jobs and Applying changes to future renewals.

These are very different processes and it is important to understand their differences.
