Get updated activities of a process instance.

Hey all.

I am currently developing a flow service in Developer to be implemented in a portlet (Designer). What I want is: get a list of all instances steps which were updated within a range of dates (format: “dd/MM/yyyy hh:mm:ss.SSS”). My main concern is which built-in service can obtain steps status, I was looking at WmMonitor package but didn’t find a service with status as output element.

Need some help here please, sorry if it’s a kind of dumb question. Thanks.

The documentation I have:
-8-2-SP1_Monitor_Built-In_Services_Reference.pdf (should I get 8.0 copy)

WM edition: 8.0

Best regards-
