Using Multiple Targets to Create a Single File With Multiple Records Types

This flow uses two targets that both point to the same flat file to write out two different record types from the HR file. There is a start record for all employees, but there is only a termination record for employees that have been terminated which is accomplished with a validate. The two different record types are designated by assigning a value to the RECTYPE field in the targets.

Refer to the sample data flow DMRCTYP for the complete example.

In the DMC:

1. Right-click an application directory, select New, and then click Flow. The Data Flow tab opens in the workspace, with the SQL object displayed.
