PM Association Query

I have PM Association Set up against the service types for an asset. The setup is as follows

Service Type A = Yearly Service

Service Type B   = Half Yearly Service

Service Type C = Monthly Service

PM Association for Service Type A is "Service Type B" and "Service Type C"

PM Association of Service Type B is "Service Type A"

The next due of all these services are due on the same day (01/01/14)

If I process R12807 on 01/01/14, how many work orders should the system create against the equipment?

Does the UBE calculates the Work Order requirement against each line in the PM schedule or against the Asset as a whole?
