Campaigns tab settings are not available in permission set
|Knowledge Article Number||000176446|
|Description||In a permission set, in object settings, campaigns will not show the tab settings as available.|
This is due to the user license associated with the permission set. The permission set must have the "Salesforce" user license type associated with it to see tab settings for campaigns. If there is another user license or no user license associated with the permission set, campaigns tab settings will not be available.
