# Enable WHODrug IDMP MPID Coding

With the 26R1 release, Safety supports IDMP MPID data when coding WHODrug products, providing greater data granularity to satisfy regional submission requirements.

This feature updates the <a href="/en/lr/01165/#whodrug-browser">_WHODrug Search_ browser</a> to include an _IDMP MPID_ column, and updates the label of the existing _MPID_ column to _UMC MPID_ for clarity. When a user codes a WHODrug product with an IDMP MPID value, Vault maps that data to the relevant _Case Product_ or _Case Drug History_.  If configured, Vault will use the IDMP MPID when generating E2B(R3) files for submission to specific agencies.

## Prerequisite
To enable this feature in your Vault, you must first <a href="/en/lr/01190/#activate-the-whodrug-dictionary">activate the WHODrug Dictionary</a>.

## Overview
To enable this feature:
* [Update object layouts and fields][1]
* Select the _Use IDMP MPID for Submissions_ checkbox on the relevant <a href="/en/lr/01202/">_Transmission Profiles_</a>, as required by the relevant agency

## Update Object Layouts and Fields {#update}
To enable Vault to populate IDMP MPID data on E2B(R3) reports, <a href="/en/lr/26387/#how-to-add-object-fields">add</a> the _Use IDMP MPID for Submissions_ field to the following object types on the _Transmission Profile_ object:
* _AS2 Gateway_
* _Email Profile_
* _Manual_
* _System Gateway_

To enable Vault to map IDMP MPID data from coded WHODrug products to the relevant object records, <a href="/en/lr/26387/#how-to-add-object-fields">add</a> the _IDMP MPID_ field to the following objects, below the _UMC MPID_ field:
* The _Base_ and _External Product_ types of _Case Product_
* _Case Drug History_
* _Product Registration_

To better differentiate between the _IDMP MPID_ field and the existing _MPID_ field, update the _MPID_ field label on the above specified objects as follows:
1. Navigate to **Admin > Configuration > Objects > [Object] > Fields > MPID**.
2. Select **Edit**.
3. Update the **Label** value to `UMC MPID`.
4. Select **Save**.
