In this dialog you can specify the group selection formula. It will be used to filter the groups that will be displayed in the report. This formula will be used on the data fetched from the database. The group selection formula can not be executed on database; i-net Clear Reports filters out the groups by itself after the records have been fetched from the database.
The return type of the formula must be Boolean.
