Effective in version 10.0, you can assign persisted mapping outputs to input parameters of the same Mapping task. Persisted mapping outputs are mapping outputs that the Data Integration Service saved in the repository from a previous workflow run. For example, you might choose to persist the latest order date from a previous workflow run. In the Mapping task
view, you can assign the persisted value to an input parameter. You might include the input parameter in a filter expression to skip rows with order dates that are less than the last date.
