A Router transformation tests data for one or more conditions and gives you the option to route rows of data that do not meet any of the conditions to a default output group.
In the following steps, you add two Router transformations to the mapping, one for each department. In each Router transformation you create two groups. One group returns True for rows where the DeptID column contains ‘SLS’. The other group returns True where the DeptID column contains ‘ENG’. All rows that do not meet either condition go into the default group.
