Production: Remaining runtime is based on remaining quantity to build regardless of actual hours reported back unless the runtime method is Hours. If a runtime method of hours, then the time remaining is based on planned hours less actual hours. If the runtime method is time per piece or pieces per hour, the quantity completed needs to be reported so that the time remaining can be calculated using the quantity remaining.
Fabrication: Remaining runtime is based on original hours minus actual hours. You can also use percent complete which calculates remaining hours based on hours reported back and percent complete reported back.
