Reporter restricts all two and three level reports to 100 rows each per applied filter.
Below is an example of what you might see, but any two or three level report would show similar symptoms.
1) Go "View Reports" > "Reports" > "User Behavior" > "Web Browsing per User and Category"
2) Click "Report Options," set the following criteria and Apply.
Date is All Dates
User is "<pick your user>"
Category is "Web Advertisements"
User Display 1 rows per page
Category Display 10 Categories per User
Site Display 100 Sites per Category
3) Click Download > Format (either PDF / CSV) > Report Data "All Rows" > Download
RESULT: On most databases, you will have more than 100 sites that are classified as "Web Advertisements," so here we'll see that the Graphical User interface shows shows more than 100 Total Sites for "Web Advertisements" category, but when we export the same report we only see 100 entries.
NOTE 1: On most reports, such as this "Web Advertisements" example, the page views and browse time of any site close to the 100 row mark is zero, which is why the Reporter software does not display more than 100 rows any two or three level report.
NOTE 2: Currently there is no way to change this to allow for more than 100 rows.
WORKAROUND: If users want to see more rows of data than the limit of 100, we suggest they run a single level report such as the "Site" report. Using the above example, a Site report that is filtered on the category of "Web Advertisements" would show you all the sites that have this data.
