Workflow Parameters

Parameters allow a workflow to receive information from, and send information back to, an external process. For example, a business process can use a Workflow Service Task to start a workflow including values collected or computed from information in a form. These values can then be used by the workflow to perform tasks. When the workflow completes, information can be sent back to the business process through the output parameters, which can then perform additional tasks using that information. Within the workflow, parameters behave just like any other token.

Mutlivalued parameters

When the Multivalued checkbox is selected, parameters can contain a delimited list of values. Default values are set by adding values in the Parameters dialog, although an input parameter is not limited by the number of default values that are set.
