Join tables are used to configure SQL join conditions in order to filter the selected data , for the current step table configuration. You can still validate the table entries of the join table. However, but it must be declared in a parent step, or a proper predefined database view should be used in the current step instead of the database table. The joined table might also be also used for selection criteria as well as for additional fields to compare.
