Mapping Parameters and Mapping Tasks

Mapping Parameters and Mapping Tasks

The Data Integration Service can use user-defined mapping parameter values when it runs a mapping within a workflow. You can use a parameter set or a parameter file for the workflow.
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.
