Possibility to link Preventive Maintenance (PM) Meter reading with Discrete Manufacturing Process in Oracle EAM (R12)

There isn't a synchronization between PM Schedule and duration time (or resource usage time) in finished Discrete Jobs

The PM Schedule is based on the entered meter readings (manually in Meter Readings form or by interface).  Usage rate (defined for meters) is used for PM Schedule calculations until the number of entered meter reading is less than "Number of Past Reading". After that, system calculates usage rate based only on entered meter readings

Difference Of Service Request And Work Request In Oracle EAM

You can probably implement your business flow using either way: Service and EAM Work Requests even there are differences between them. The main difference is that agents can view work orders created in Oracle Enterprise Asset Management related to the service request, but the life cycle of the work order is not in any way tied to the service request life cycle. Closing work orders tied to a service request does not close the service request and vice-versa. This is not the same when using work requests

Other differences: Normally, SRs are used when maintaining instances owned by customers while WRs are used when maintaining own asset numbers. we can use approval workflow for WRs and not for SRs. Using SRs you need to create a repair order then to generate work orders while using the WRs, the WOs are generated directly
