Work order tracking

Work order tracking

I have jobs that require 2 people to do simultaneously so two people need to clock into the same work order and complete the same number of parts.

However, If one person enters the WO quantity as complete the second person cannot enter any quantity, they have to enter a 0.
But when I run the efficiencies for the workers the one who entered a zero appears as if they did nothing.
I set up the router to requite to employees.
I have tried having them check the helper option but still have the same problem.
