Workflow elements process data that they receive as input parameters, and set the resulting data as workflow attributes or output parameters.
Read-only workflow attributes act as global constants for a workflow. Writable attributes act as a workflow’s global variables.
You can use attributes to transfer data between the elements of a workflow. You can obtain attributes in the following ways:
- Define attributes when you create a workflow.
- Set the output parameter of a workflow element as a workflow attribute.
- Inherit attributes from a configuration element.
