Auto-Populate Inputs and Outputs
You can automatically populate the inputs and outputs of a step from its underlying IS service, Web service, task, or rule. This underlying information is known as the service signature.
Auto-populating step inputs and outputs allows Designer to do the data mapping of the step inputs and outputs. If you do not auto-populate with the service signature, you must manually map the data to the appropriate service. Click the Edit Data Mapping link on the Inputs/Outputs page in the Properties view, or right-click a step and click Edit Data Mapping.
Note: | Most steps have a single Edit Data Mapping right-click menu option. Call activity steps and task steps have two mapping options in their context menus: Edit Input Data Mapping and Edit Output Data Mapping. Empty steps do not have data to map, so they have no data mapping capability. |
For more information about data mapping in Designer, see in webMethods Service Development Help.
To auto-populate a step input or output
1. Select a step in the process editor.
2. On the Inputs / Outputs page in the Properties view, click 
Auto-populate inputs based on service signature in the Inputs section or Auto-populate outputs based on service signature in the Outputs section. Note: | Text entered in the Description field is included in the HTML Documentation Report. |
