Instead of creating a new case type for tracking orders, as every time they need to track the previous order, a new case type would be created, we can handle it in the portal.

Please find below steps to achieve it :

1) Add an item for the menu in the portal(ex: caseworker).

2) On the action set of the menu item, configure on click and action as a Harness(create new Harness).

3) In Harness rule, include a newly created section.

4) In the section use table layout and source it with Report Definition and use required columns to show.

Thanks
