Parameters work as placeholders that point to a value. When you add a parameter in a plan, the workflow uses the value that the parameter points to at run time. You can change the value to change the value that the workflow uses.

You can create parameters within a project for connections, owners, and entity criteria. Add a default value when you create the parameter. You can override the value and enter different values or use different criteria parameters in the workflow to create different data each time you run the workflow.

You can create the following types of parameters in a project:

Connection parameter. A placeholder for source or target connections.
Owner parameter. A placeholder for source or target schema owner names.
Criteria parameter. A placeholder for values that you include in filter criteria in an entity.

Use criteria parameters when you create an entity and select the required parameter when you run the workflow.

Select parameters from the list of available parameters when you create a plan. You can choose from global and project parameters. Before you run a workflow, you can create a sample parameter file that contains all parameters included in the plan. Choose to use the parameter file as is or to edit the parameter values and use the file in the workflow. You can also edit parameter values in Test Data Manager when you run the workflow.
