Campaign Influence on Opportunities is covered, along with the Campaign ROI Analysis Report. I originally recorded this lecture for my upcoming Salesforce New User Training course, and felt it would be beneficial for your studies toward the Administrator Certification. Campaign Influence has recently been added to the Admin Exam, so I wanted to keep you up to date.
The Enhanced Page Layout Editor is also demonstrated in this lecture, where we add the Campaign Influence related list. I also demonstrate how ROI is measured between campaigns and opportunities as we go through the Campaign ROI Analysis Report.
