When you run a workflow, you can specify a parameter set at run time. The parameter set contains user-defined parameter values. You must add a parameter set to the application when you deploy the workflow. You can include multiple parameter sets when you deploy the workflow and run the workflow with a different parameter set for each run.

You can also add a parameter set to a Mapping task. When you add a parameter set to a Mapping task, the parameter set overrides the mapping parameter values or the workflow parameter values that you defined.

When you run a workflow, you can specify a single parameter file for the workflow. You define user-defined mapping parameter values within a mapping or mapplet element in the parameter file. Define workflow parameter values within a workflow element in the parameter file.

When you run the workflow with a parameter file or a parameter set, the Data Integration Service applies all the user-defined mapping parameter values and workflow parameter values.
