DD_UPDATE

DD_UPDATE

Flags records for update in an update strategy expression. DD_UPDATE is equivalent to the integer literal 1.
Use the DD_UPDATE constant in the Update Strategy transformation only. Use DD_UPDATE instead of the integer literal 1 to facilitate troubleshooting complex numeric expressions.
When you run a workflow, select the data-driven update strategy to write records to a target based on this flag.
