What's a good way to determine if the subsidiaries feature is enabled in the NetSuite account? I don't see an option in Enable Features.

its id is

SUBSIDIARIES

I can understand the confusion, it's not listed on: Feature Names and IDs article (which is linked on the runtime.isFeatureInEffect(options) page)

Thanks! I was using this to check for features being enabled. What's the difference?

config.load({
  type: config.Type.FEATURES,
});

The config.Type.FEATURES enum specifically loads the config from the enable features page. Which the oneworld/subsidiaries feature isn't a part of. My guess: the Oneworld feature isn't there because it's a very fundamental account feature

Good enough for me. Thanks for everyone's help!
