After exporting the schedule to Primavera Risk Analysis, the project final date is not the same. Some activities don't have the same start and finish dates.
You will have to ask the support technicians from Oracle, because there is nowhere mentioned about this procedure. I have tried looking for the Export function, but I couldn't find anything.
Use the official website to learn more about it and get in touch with the support team. They will provide the necessary details to get the job done.
