To exclude rows from your report, you can input a filter formula in the Report section of the designer:
This normally specifies which rows to include, but you can also use the "is not" or "different than" symbol which is "<>" to specify which to exclude.
So as in the example above we can construct a formula saying:SQL
[Customer Email] <> "firstname.lastname@example.org" AND [Customer City] <> ANY("London", "Brisbane", "Sydney") AND [Customer Country] <> NULL
Which would translate to "only include rows which do NOT have an email of email@example.com and which do NOT have their city as London, or Brisbane or Sydney and which do NOT have an empty Country.
