MES quantity display customization

I am trying to display the total run quantity, and previously reported
completed quantity (labor quantity information)on my END ACTIVITY
screen in MES, through customization. The data I need is located in
JobOper.QtyCompleted and JobOper.RunQty
However, JobOper is not linked/available as a data source for the END
ACTIVITY screen. How can I get this data linked/displayed on this
screen.
