If Powder is setup as one operation with a crew of 4 and each person clocks on and off the job, then 3 people have to enter a 0 quantity and the final person enters the complete quantity. This method gives us a correct WIP quantity. But the 0 quantity entries for the other people make their earned hours 0. It is because earned hours is a function of labor quantity. The 0 quantity also affects efficiency and productivity numbers.
I tested using Time-Backflush quantity for the MES labor entry process on Powder. Each of the 4 operators just entered time and the quantity entry was greyed out. My hope was that this might solve my quantity issue. But all the labor enters for quantity on powder just show 0. Now every powder operator has 0 for earned hours. This is not a solution.
