## Scaled change properties {#installed-with-scaled-change__section_properties}

To view or edit them, enter <kbd class="ph userinput">sys_properties.list</kbd> in the navigator text box and filter for sn_major_change.  
Note:  
Activate the Major Change (com.sn_major_change) plugin to get these components. For more information, see [Activate a plugin](https://www.servicenow.com/docs/access?context=t_ActivateAPlugin&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).
{#installed-with-scaled-change__table_scaled_change_properties__entry__3}

| 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` |
[Table 1. Scaled change properties]

{#installed-with-scaled-change__table_scaled_change_properties}  
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 {#installed-with-scaled-change__section_data_retention}

The Major Change plugin installs the following data archive rule. For general information about data archiving, see [Activate Change Management - Data Archiving](https://www.servicenow.com/docs/pZrwCVO74_z0gjxzPQ6gfw "You can activate the Change Management - Data Archiving plugin (com.glide.auxdb) if you have the admin role. This plugin includes demo data and activates related plugins if they are not already active.").
{#installed-with-scaled-change__table_scaled_change_archive__entry__2}

| 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. |
