Explaining Testing and Monitoring of a PO Process

There are several ways of starting a process, depending on its purpose and starting point. In order for a process to start, it must have an active version. The methods for starting a process include the following:

• Starting processes from the Process Repository

  Start the process from the Process Repository tool that is integrated in the SAP NetWeaver Administrator. This method is mostly used for test purposes.

• Starting processes by Web services

  This method can be used to start a process from the Web Service Navigator, Web Dynpro applications, or from a Web service client.

• Starting processes from the Debugger

  You can start a process from the Debugger that is integrated in the SAP NetWeaver Developer Studio (NWDS).

For testing purposes, BPM processes can be started using the Process Repository in the NetWeaver Administrator.

For testing purposes, Business Process Management (BPM) process can be started using the Process Repository in the NetWeaver Administrator. Although users typically do not use the NetWeaver Administrator BPM processes, this application provides a Web service that allows you to start a BPM process through a standard wWeb service call. This includes processes with UIs built in Web Dynpro, Visual Composer, and similar technologies. These Web services can be used by any application.

The Web services can include data, which can be passed from the UIs to the processes that are started. The data stored in the process context can influence the process flow or be processed in process activities.

The SAP NetWeaver Administrator includes a system status monitor that allows you to view the configuration of processes and tasks. This monitor is accessible at http://<host>:<port>/nwa, under Availability and Performance → BPM System Overview.

The figure shows the BPM System Overview screen in the Availability and Performance tab of the NWA.

To view a comprehensive overview of all running and finished processes in SAP NetWeaver, choose Operations → Processes and Tasks → Manage Processes. From here you have access to all process details.

The figure, Process Management Overview, progresses as follows:

1. Once a process is selected, all the currently running instances of the process appear.
2. Actions such as Suspend and Resume can be chosen for currently running process instances.
3. Choosing the Show Process Flow button opens a new window with a graphical representation of the selected process. In the example the green dot indicates that the process in currently in waiting. This process waits on the intermediate message event waitOfMessages.

You can monitor messages by choosing the link Show Related PI Messages from the Details tab. The message monitor that appears displays XI protocol messages for the selected process.

The History tab allows you to view the steps of the selected process according to the option chosen in the Show drop-down box. In particular, you can view outgoing and incoming messages. The Group by drop-down box allows you to filter what appears in the display.

The current values of context data in the register for individually selected data objects is shown in the Context Data tab.
