# Enable Inbox Item Follow-Up Case Compare

Learn how to update your Vault's configuration to enable the _Inbox Item Follow-Up Case Compare_ page for _Inbox Item_ promotion.

## About the Feature

With the 21R3 release, Veeva Safety provides the _Inbox Item Follow-Up Case Compare_ page, which allows users to compare data from a new _Inbox Item_ to a previous _Case_ version during case promotion. After you have enabled this feature, see <a href="/en/lr/01196/">Configure the Inbox Item Follow-Up Case Compare Layout</a> for details about how to customize the page and  <a href="/en/lr/01136/">Inbox Item Follow-Up</a> for details about how users use the page.

With the 22R3 release, we provided additional capabilities to turn off auto-calculation on the page for _Inbox Item_ promotion. See the [(22R3) enablement instructions][1] to configure your Vault for the updated feature.

## Permission Sets 

Ensure the _Administration Actions_ <a href="/en/lr/23647/">permission set</a> has _View_ permission for the _Case Promotion Settings_ page so the appropriate users can <a href="/en/lr/01196/">configure the page</a>.
