I'm new to Salesforce, and had a question about Profiles and permission sets
Suppose I have a user Bob with the following profile :
Standard User :
Can create and edit most major types of records, run reports, and view the org's setup. Can view, but not manage, campaigns. Can create, but not review, solutions. Can edit personal quota and override forecasts. (Help)
Bob can create accounts, contacts and opportunities and whatever.
I have edited this Profile so that it can't access a custom field on the Account object called Language.
Knowing that there are several people with this profile, I just want Bob to access this field.
I created a permission set. In Object Settings, under Accounts, I selected both Read Access & Edit access for the Language field and assigned the permission to Bob.
Is it enough for Bob to access the field ?
The reason I'm asking the question, is that I can still see rows with No access (on permission set page) and wondering if permission sets can restrict some permissions the user had with his profile ?
