I have a question about change sets that seems basic but I haven't been able to find a definitive answer. Essentially, I have a situation in which an admin wants to deploy 3 new fields from sandbox to production. They have created a change set with these three fields added as components and ALL of our profiles in the 'Profile Settings For Included Components' section of the change set. Am I correct in saying that ONLY field level permissions related to these three custom fields will be updated in the production org?
This is my understanding though I have never been able to find definitive documentation on this. There have certainly been in these profiles in production since this sandbox was updated and I fear reverting or altering these changes. I've certainly looked at this document but it's a bit confusing. Any help, guidance, other documentation would be helpful. Thanks!
