Recommendations for Using Code Sets and Code Set Bundles
As an admin, it’s up to you to populate these objects with the codes your organization needs. As the volume of required codes can be immense, we recommend that you use the Salesforce Data Loader to import code data into your orgs.
Data integrity in your code database is vital to the smooth functioning of your organization. Especially if you’re in the payer industry, it’s likely that you don’t want your users to modify codes or add new ones. Such code changes can interfere with the automated approval processes you’ve set up and result in unintended authorizations. Therefore, we recommend modifying the access permissions on these objects after you populate these objects with the data your organization needs. You can give your users Read-Only access to these objects, or even prevent new record creation in them after your initial data loading.
