Set and create Problems to define which Problems can be reported when creating a Work Order.
Officetrax comes with 13 default problems to make communication with other Officetrax users easier (standardizes problem names). These problems cannot be deleted. They can be edited, however, when dispatching using one of these default problems, another user may only see the default name given rather than your edited/custom name so it is recommended that you leave the default problems as-is aside from adding your overrides, expenses, and trades.
The parent problems are going to be one of the default Officetrax problems. This helps you organize/categorize your problems further into sub-problems etc.
You can only delete sub-problems you've created.
