# Enable Copy Datasheet Expectedness Justification to Case Assessments

Learn how to configure your Vault to map adverse event expectedness rationales on _Datasheets_ to _Case Assessments_ and _Localized Case Assessments_.

## About the Feature

With the 24R3 release, Vault Safety supports adding rationales for adverse event expectedness to _Datasheets_. When populated, Vault copies text in the new _Expectedness Justification_ field on _Datasheets_ and populates the text in the same field on _Case Assessments_ and _Localized Case Assessments_. This feature supports users when entering expectedness justifications in the J2.11 Other References data element of PMDA E2B(R3) reports.

After you have configured this feature, see the following articles for more information:

* <a href="/en/lr/01287/#expectedness-section">Case Field Reference</a>
* <a href="/en/lr/891324/#expectedness-just">Localized Case Field Reference</a>
* <a href="/en/lr/696910/#expectedness-just">Complete Intake and Process Cases for the PMDA</a>

## Update Object Layouts

To support this feature, you must add the _Expectedness Justification_ field to the applicable layouts for the following objects:

* _Case Assessment Expectedness_

To add the field:

1. Navigate to **Admin > Configuration > Objects > [Object] > Layouts > [layout]**.
2. In the _Details_ section, add the **Expectedness Justification** field.
3. Select **Save**.
