Currently the System is limited with its functionality to manage Work Orders, there are 2 options that you can do to manage work orders.

At any stage you wish to make edits or add notes, this can be done for the Work Order. Go to Requests > Work Orders > Click 3 Dots > Select Add Notes or Edit Work Order.

One of the common changes is changing the "Work Order Status" in Admin Details to reflect the status of the Work Order as it gets completed.

To Mark the Work Order as closed go to Requests > Work Orders > Click 3 Dots > Select Mark Closed

This will archive the Work Order and move it to the closed Tab.
