Business Case - 

The user wants to adds a gauge meter at operation level so that while completing the Work Order Operation, then the user will record the reading and if it is out of range then it will trigger a Corrective Work Order.

Now the problem is in Oracle attaching meters to Asset is possible but attaching meters to Work Definition or operations is not possible.

If we attach the meter and make it compulsory to record reading at Work Order completion then for every work order for that asset they have to record the meter reading which is not right and feasible for them.
