# Enable PMDA E2B(R3): Prevent Export of Unsupported UCUM Codes

Learn how to configure your Vault to prevent the export of unsupported UCUM codes on PMDA E2B(R3) reports.

## About the Feature

With the 24R2 release, Vault Safety prevents the export of unsupported Unified Code for Units of Measure (UCUM) codes to PMDA E2B(R3) reports. Vault considers a code to be unsupported if the related unit of measurement is not listed in the **Agency Units of Measurement** object for the PMDA agency. This feature reduces instances of PMDA E2B(R3) files being rejected for unsupported codes and the need to route corrections to Global Case Processors.

When a Global or Domestic Case includes any **Strength**, **Dose**, or **Cumulative Dose to First Reaction** units of measurement that are not supported by the PMDA, those unsupported units are captured in a **Validation Criteria** record. Depending on your configuration, unsupported units of measurement may be excluded completely or Vault can export those unit values as <code>{DF}</code>. If a unit is excluded, the associated number value is also excluded from the export.

This change impacts the following PMDA E2B(R3) data elements:

* **G.k.2.3.r.3a Strength (number)** and **G.k.2.3.r.3b Strength (unit)**
* **G.k.4.r.1a Dose (number)** and **G.k.4.r.1b Dose (unit)**
* **G.k.5a Cumulative Dose to First Reaction (number)** and **G.k.5b Cumulative Dose to First Reaction (unit)**

After enabling this feature, see Prevent Export of Unsupported UCUM Codes in <a href="/en/lr/696896/#prevent-ucum-export">Report to the PMDA</a>.

## Prerequisite

You must have enabled <a href="/en/lr/01419/">Support for Unconstrained UCUM for Test Result Units</a>.

## Configure Export of Unsupported UCUM Codes

There are two (2) settings that control how Vault manages unsupported UCUM codes as follows:

* **PMDA E2B: Do not export UCUM code not supported by PMDA:** When selected, this setting prevents the export of unsupported UCUM codes to PMDA E2B(R3) reports.
* **Export {DF} for unsupported UCUM code if number is specified:** This option is available only when the **PMDA E2B: Do not export UCUM code not supported by PMDA** option is selected. When selected, this setting exports <code>{DF}</code> in place of unsupported UCUM codes on PMDA E2B(R3) reports.

Complete the steps below to configure these settings in your Vault.

1. Go to **Admin > Settings > Submission and Distribution Settings** and select **Edit**.
2. Select the **PMDA E2B: Do not export UCUM code not supported by PMDA** checkbox.<br>A subsetting appears.
3. Optional: Select the **Export {DF} for unsupported UCUM code if number is specified** checkbox.
4. Select **Save**.

## Recommended: Validation Criteria Updates

Once this feature is enabled, we recommend setting the following **Validation Criteria** for unsupported UCUM codes to **Inactive**:

* **PMDA.G.k.2.3.r.3b**
* **PMDA.G.k.4.r.1b**
* **PMDA.G.k.5b**

1. Go to **Business Admin > Objects > Validation Criteria**.
2. In the **Agency** column filter, select the **PMDA** checkbox and then select **Apply**.
3. For each **Validation Criteria** listed above, select the record and change its object status from **Active** to **Inactive**.
   1. On the **Change Object Status** dialog, select **Yes**.
