# Manage the Japan Drug Dictionary

Veeva Safety supports the Japan Drug Dictionary (JDD) when processing domestic and _Localized Cases_ for Japan. This feature includes lookup and coding of _External Products_ with JDrug codes, which are exported to PMDA E2B(R3) reports when generating _Transmissions_. When working with _Company Products_ in your _Product_ library, Vault maps codes from the _Local Product Code_ field on _Japan Product Registrations_.

When <a class="external-link " href="https://rn.veevavault.help/en/gr/safety-central-dictionary-updates/#jdd-versions" target="_blank" rel="noopener">new JDD versions<i class="fa fa-external-link" aria-hidden="true"></i></a> are released, they are uploaded to the central dictionary. You control which JDD version Vault uses for JDrug coding.

### Prerequisites

Consider the following prerequisites for managing the JDD:

* Your Admin must <a href="/en/gr/01348/">enable the Japan Drug Dictionary</a>.
* Your organization must maintain a valid JDD license to use the centralized JDD service.

Vault also supports cross-referencing JDrug and WHODrug codes during case processing using the <a href="/en/gr/782230/">WHODrug Cross Reference Tool (CRT) Japan</a>.

## Update the Active JDrug Version
The _Active Version_ field on the _Japan Drug Dictionary_ displays the following message when your Vault is out-of-sync with the latest JDD releases: `The list of available JDrug versions is out of sync with the server. Please sync the JDrug versions to update the list.`

When new JDD versions become available, you can activate them to make the latest codes available during domestic and _Localized Case_ processing for Japan:

1. Navigate to **Business Admin > Objects > Dictionaries > JDrug Dictionary**.
2. To sync the list of available JDrug versions, from the **All Actions** menu, select **Fetch Dictionary Releases**.
3. To activate a JDrug version:
    1. Select **Edit**.
    2. In the **Active JDrug Version** field, select the desired dictionary version from the picklist.
    3. Select **Save**.

When the import is complete, Vault sends you an email notification and sets the status of the _JDrug Dictionary_ to _Active_. When the <a href="/en/gr/01163/#browse-and-code-jdrug-products">_JDrug Browser_</a> is used, the search results are based on the version selected.
