By assigning a content set to a report request, you can generate hundreds of similar reports in a single run. The content set controls how the numerous reports differ from each other. For example, assume your organization has 50 departments and that Department is one of your account segments. Also assume that you already have an FSG report for travel expenses, which you run weekly. By using a content set with your existing report definition, you can print a travel expense report for each department, in one report request. You can then distribute the reports to the 50 department managers for review purposes.

Content sets are similar to row sets and actually work their magic by overriding the row set definition of an existing report. The subtle report variations discussed in the previous paragraph are achieved by the content set altering the row set account assignments and/or display options.
Note: A content set can be saved as part of a report definition, or can be added dynamically at the time you request an FSG report.
