# Enable Partial Date Support for Dose-Level Expiration

Learn how to enable partial-date support for Dose-Level Expiration Date in your Vault.

## About the Feature
Vault Safety now supports partial date entry at the Case Product Dosage-level for Expiration Date
(see the Dosages Section under <a href="/en/gr/01287/#dosages-fields">Case Field Reference</a>).

Depending on the configuration of your Vault, enablement may not be required. The new `expiration_date_idate__v` field is added to the Case Product Dosage section control automatically,
however, you may need to grant permissions to the field.

## Provide the Edit Permission for the Case Product Dosage Object

1. In the Admin area, go to **Users & Groups > Permission Sets**.
2. Open the relevant permission set, for example **Case Entry Actions**.
3. If the Edit permission is not checked in the **All Objects** row, go to the **Case Product Dosage** row and give the Edit permission for the **Expiration Date** (`expiration_date_idate__v`) field.
4. Apply this to all relevant permission sets that should have Edit access.
