Job cheduling multiple resources on one operation

I am using AX 2012 R2.

I have 2 resources that have capability to produce cake:-

  • oven A capacity 100 cake/hr

  • oven B capacity 200 cake/hr

I have a production order to produce 2400 cakes.

In the route config, I assign:-

  • Setup Formula: Capacity

  • Resource Quantity: 2

  • Required: Capability: Produce Cake

  • Factor: 1

  • Run Time: 1

  • Process Qty: 1

The best expected result would be:-

  • oven A: 8hr (100 cake/hr * 8hr = 800 cake)

  • oven B: 8hr (200 cake/hr * 8hr = 1,600 cake)

However, the current result is:-

  • oven A: 12 hr

  • oven B: 12 hr

Is there anyway I can get the best result?
