On the Work Order and Round Order Resource Lines, you can use two new fields. Both fields are hidden by default.
Line Status - as a technician, you can use this information to define what is the current status of your work defined in the specific line.
Notes - as a technician, you can put some notes about your current work that are visible to any user visiting this work order.
These values are propagated to the posted document when the Order/Round order is closed. Fields are also hidden by default.
