HistoryRetentionPolicy
Represents the policy for retaining field history
data. By setting a policy, you can specify the number of months you want to maintain
field history in Salesforce
and the number of years that you want to retain field history in the
archive.
This component is only available to users with the “RetainFieldHistory” permission.
Declarative Metadata File Suffix and Directory Location
Field history retention policies are defined as part of a standard or custom object. You can set field history retention policies for objects individually. See CustomObject for more information.
Fields
| Field Name | Field Type | Description |
|---|---|---|
| archiveAfterMonths | int | Required. The number of months that you want to keep field history data in Salesforce before archiving. You can set a minimum of 1 month and a maximum of 18 months. If you don’t set a number, the default is 18 months. (That is, Salesforce maintains data for 18 months before archiving.) |
| archiveRetentionYears | int | Required. The number of years that you want to retain data in the archive. You can set a minimum of zero years, and a maximum of 10 years. If no number is set, the default is 10 years. |
| description | string | A text description for the history retention. |
| gracePeriodDays | int | The number of days of extra time after the archiveAfterMonths period before the data is archived. The gracePeriodDays interval applies only to the first time that the data is archived; because all the data is copied the first time, the operation may take longer than subsequent times when only the data that changed since the last archival operation is copied. The gracePeriodDays provides extra time for the administrator to prepare the organization before the initial archive operation. You can set a minimum of zero days and a maximum of 10 days. If no number is set, the default is 1 day. |
