Hi Michael,
To the best of my knowledge, it is not possible to run BOP with data from simulation version,
But after going through your requirement what i could understand that you want to validate the capacities set in allocation, you can run BOP in simulation, which in a way doesn't have anything to do with data from simulation version (copy version), but it will not update the date into ECC.
So after running BOP in simulation mode, you can check the log and validate the results as per your need.
