Assigning Persisted Outputs to Mapping Task Input

You can bind persisted mapping outputs from a Mapping task to the input parameters of the same Mapping task for the next time the workflow runs.

Assign the persisted latest order date value from the Mapping task as the input parameter to the same Mapping task. Configure a Filter transformation that uses a Last_OrderDate_Parm parameter to select which orders to process. The filter expression to select input rows is

Order_Date > Last_OrderDate_Parm

Click the Mapping task icon in the workflow to view the Mapping task
