Define Targets Based on the Data Object

Define Targets Based on the Data Object

You can configure the Write transformation to define target columns based on the associated data object.
When you define target columns based on the data object, the Write transformation contains dynamic and generated ports.
You can choose to create or replace the target at run time. You can retain target keys when you create or replace the target if the column names match. You can configure rules to ensure that column names match.
Configure this functionality on the
Ports
tab of the Write transformation for flat file and relational targets.
