# Enable WHODrug Link Korea

With the 25R2 release, Veeva Safety can cross-reference Korea Drug Dictionary and WHODrug codes for case processing and submissions using WHODrug Link Korea. This is useful when coding _External Products_ for domestic _Cases_ and foreign _Localized Cases_ reportable to the MFDS, eliminating manual code entry, such as in the following scenarios:

* Adding the applicable WHODrug code when processing a Korea domestic _Case_ with an _External Product_ coded using a Korea Drug Dictionary code.
* Adding the applicable Korea Drug Dictionary code when processing a Korea foreign _Localized Case_ with an _External Product_ coded using a WHODrug code.

You control which version of the WHODrug Link Korea your Vault uses for coding.
