Work Order management takes place in the DPS directly from the Action List widget through a new embedded panel, Work Orders.

Other than configure the Actions to let your DPS users manage Work Orders, you must:
Place the Action List widget in a thing view, for instance, you can add the Maintenance tab.
Configure the User Permissions:
READ_WORK_ORDER: Required to display the Work Orders panel.WRITE_WORK_ORDER: Required to edit any work order property (e.g., Service ID, Transport document, Start/End date).WORK_ORDER_MANAGER: Required to change the Work Order status, including APPROVED or REJECTED.
Generally, this permission is assigned to Service Managers.WORK_ORDER_EXECUTOR: Required to change the Work Order status to EXECUTION and COMPLETED.
Generally, this permission is assigned to Technicians.
The Work Orders section is only visible to users having the READ_WORK_ORDER permission.
When entering the details of a Work Order to change any property, the WRITE_WORK_ORDER permission is required.
Note that the Work Orders panel is present only when in the context of a thing. If the Action List is placed in a general page, the panel won’t be displayed.
