Workflow parameters

Workflow parameters contain data that can be used in various steps of the workflow. Every step of the workflow has access to the complete set of the workflow parameters.

The workflow starts with the complete set of these parameters. The values of the parameters are specified through one of these means:

• Input parameters that are passed to the workflow at the moment it starts
• Initial value, specified in the workflow definition

  Every parameter that is not an input parameter, must have an initial value.

When the workflow reaches the End step, every parameter will have a value. The values for the output parameters are reported back to the initiator of the workflow.

A parameter can be an input parameter, an output parameter, both input and output, or neither input or output.
