Localization Context Filtering Support for Scripts in Bundles
You can use localization context filtering for SuiteScript 2.0 user event and client scripts in bundles. If a script in a bundle has localization context filtering, it works in every target account where you install the bundle.
A record’s localization context sows which countries are linked to it. Set up localization context filtering in the Localization Context field on the Context Filtering subtab of the script deployment record. This controls which records user event and client scripts run on, based on their localization context. For example, if you set a script's localization context to France, it only runs on records with a localization context of France—not on records with other contexts.
