Starting a Process Using Web Services

Use

You can start a process and retrieve the process output and status using the GPProcessDiscovery Web Services (WS) that Guided Procedures (GP) provides. With these services, you can start a process from any process template in the gallery.

You can consume the Web service using any Web service client. In GP, you create a Web service callable object to consume the service.

For more information about the specifics of WSIL and WSDL generation and content, see Consuming the GPProcessDiscovery Web Services .

Prerequisites

You have created and configured a destination for the Web service.
More information: Configuring Destinations for WS Callable Objects
You have the appropriate permissions to work with GP design time.
More information: Setting Up Portal Roles

Procedure

Create the callable object as described in Exposing Web Services as Callable Objects .
- Select the destination you created previously for the Web service.
- Select a process template.
- Choose one of the following operations:
  - StartProcess
  - GetProcessInfo
  - GetProcessResult
Test the callable object in GP design time or include it in a process to test it in runtime.

Note

You can retrieve the process ID from SAP NetWeaver Administrator → Availability and Performance Management → Process Monitoring → Guided Procedures → Process Instances.
