#### Result: Add a Case Product {#result-case-product}
When you save the changes to the _Case Product_ after selecting a product code, Vault adds the selected product, Local MPID, and manufacturer to the _Korea Drug_ field. For _Localized Case Products_, Vault also populates the _Registration Holder/Applicant_ fields. To remove the code, edit the record and select **Clear Selection**.
#### Result: Add a Case Drug History {#result-case-drug-history}
After you save a drug code, Vault populates the _Korea Drug_ field with the Korean drug name and the MFDS Medicinal Product Identifier, when available. Vault uses the Korean data to perform a dictionary lookup for the related English drug data, then populates the English product name and corresponding MPID code in the _WHODrug_ field, as well as your Vault's active WHODrug dictionary version and a message describing the result of the cross-reference.
When you save a domestic _Case Drug History_, Vault maps the _Korea Drug_ and _WHODrug_ values to corresponding Korean _Localized Case Drug Histories_.
To remove the code, edit the record and select **Clear Selection**.
