How do we create a campaign hierarchy in Salesforce?

<div data-md=”61″ lang=”en-IN”><div aria-level=”3″ role=”heading” data-attrid=”wa:/description” data-hveid=”CAwQAg”>Each campaign can have one parent campaign, but an unlimited number of sibling campaigns. To set up campaign hierarchies, add the Parent Campaign field to your campaign page layout and enable the campaign hierarchy statistics fields. Use field-level security to make the fields visible.
