To organize related marketing initiatives and simplify reporting, Salesforce utilizes Campaign Hierarchies. A hierarchy allows an administrator to link multiple campaigns together using the " Parent Campaign " field. In this scenario, the admin should create a " Parent " campaign to represent the entire networking series and then create individual " Child " campaigns for each monthly event. This structure provides two major benefits: it allows the sales rep to see the specific performance (ROI, members, responses) of a single monthly event, and it uses " Hierarchy Total " fields to automatically roll up all those metrics to the parent level. This provides a holistic view of the entire series ' success without requiring complex manual calculations. Using the same name for campaigns (Option A) leads to data confusion, and while member statuses (Option B) are useful, they do not provide the structural " series vs. month " reporting required here. Campaign Hierarchy is the standard architectural approach for multi-touch or recurring marketing efforts.
