How to reassign a task to another user in Windchill ?

@rzemmali,

To do this grammatically (using API), you can use below code snippet:

ObjectIdentifier oid = ObjectIdentifier.newObjectIdentifier("wt.workflow.work.WorkItem:319469");
WorkItem wi = (WorkItem) PersistenceHelper.manager.refresh(oid);
System.out.println("WorkItem Name: " + wi.getIdentity());
		
System.out.println(" Workitem Owner (Before delegate): " + wi.getOwnership().getOwner().getIdentity());
		
WTUser user = wt.org.OrganizationServicesHelper.manager.getAuthenticatedUser("shirish");
WTPrincipal principal = (WTPrincipal) user;
wt.workflow.work.WorkflowHelper.service.delegate(wi, principal); 

System.out.println(" Workitem Owner (After delegate): " + wi.getOwnership().getOwner().getIdentity());

I hope this will help you.

Regards,

Shirish
