HowTo achieve process instance of scheduled process

[source: http://peoplesoft.ittoolbox.com/groups/technical-functional/peopletools-l/peoplecode-to-discover-process-instance-of-scheduled-process-892219]

In 8.44, when you schedule a process, you are returned a ProcessRequest object which has as a property - ProcessInstance. Here is the entry from PeopleBooks:

--- ProcessInstance Description ---
This property is a system-generated identification number. PeopleSoft Process Scheduler assigns a ProcessInstance at runtime to each process or job it successfully schedules.

This property is read-write. 

<* Example starts *> 

&RQST = CreateProcessRequest(); 

&rec = GetRecord();

/* Set all the Required Properties */ 

&RQST.RunControlID = ; 

&RQST.ProcessType = "Application Engine"; 

&RQST.ProcessName = ; 

&RQST.RunDateTime = &rec.STARTDATETIME.Value; 

/* Schedule the Process - get the instance and change the runstatus to HOLD*/ 

&RQST.Schedule(); 

If &RQST.Status = 0 then 

    /* process successfully scheduled, ***get the instance*** */ 

    &ProcInst = &RQST.ProcessInstance; 

    /* change the runstatus to HOLD */

    If All(&rec.CS_DEPEND_NAME.Value) Then 

        &RQST.RunStatus = "4";

        &RQST.UpdateRunStatus(); 

    End-If; 

Else 

    /* do error processing */
End-If;
