Scaled change properties

Property	Description	Default value
`sn_major_change.affected_ci_threshold`	Sets the maximum number of affected configuration items allowed on a Primary change before the threshold enforcement mode takes effect.	`2000`
`sn_major_change.threshold_enforcement_mode`	Determines the behavior when the affected configuration item count on a Primary change exceeds the value in `sn_major_change.affected_ci_threshold`. Set to `warning` to log the condition and still allow Child change generation, or `blocking` to log the condition and stop Child change generation.	`warning`
`sn_major_change.child_change_generation_batch_size`	Sets the maximum number of configuration items processed together in a single Child change generation batch.	`500`

Note: If sn_major_change.threshold_enforcement_mode is missing or set to a value other than warning or blocking, the system falls back to warning mode.

The system logs the condition, whether the mode is warning or blocking.

Data retention

The Major Change plugin installs the following data archive rule. For general information about data archiving, see Activate Change Management - Data Archiving.

Rule	Description
Archive Child Changes	Archives a Child change (a Change Request [change_request] record with the Primary change request field set) six months after its Primary change's Active field is set to false.
