When you create a parameter set, you choose a mapping or workflow to use the parameters. After you choose a mapping or workflow, you can manually enter parameters in the parameter set or you can select parameters that are already in the repository for the mapping or the workflow.

You can use parameter sets for different situations. For example, you might use a specific parameter set when you run a workflow in a test environment.

You use a parameter set with a mapping, Mapping task, or workflow. You can add one or more parameter sets to an application when you deploy the application. You can add a parameter set to multiple applications and deploy them. To use a parameter set with a workflow or mapping, you must add the parameter set to the application when you deploy the workflow or mapping.

The following image shows a parameter set that contains parameters for two mappings:

The parameter set contains the following information:

Object Name

The name of the mapping, mapplet, or workflow that contains the parameter definition.

Parameter Name

The name of the parameter in the mapping, mapplet, or workflow.

Value

The value of the parameter to use at runtime. The value of the parameter in the parameter set overrides the parameter value in the mapping or workflow.

Type

The type of the parameter. Example parameter types include strings, numeric types, connections, port lists, sort lists, and date\time parameters.

The parameter type that you specify in the parameter set must match the parameter type in the mapping, Mapping task, or workflow. If the parameter types do not match, the mapping, Mapping task, or workflow uses the default value for the parameter.

When you use a parameter set to configure mapping parameter values, the link between the parameter set and the mapping depends on the project where the mapping is defined. If the project name is changed, you must re-establish the link.

To re-establish the link, edit the parameter set and re-select the mapping that uses the parameter set.

For example, you have a project named P1 that includes a mapping m_1 that uses a parameter set ps_1. You change the project name to P2. Subsequently, you must edit the parameter set to re-select mapping m_1.
