Pretty tough to understand what you might be asking. Generally speaking the OS is created as much as possible looking at today or the future. Of course one needs the Org Structure to reflect 'real time' by inputting what is viewed as the 'current' information and most accurate as known by the organization. Once the OS is input then of course users will enter Personnel Administration to reflect the real time status of employees using the effective dates: Start and To.
If you are looking at 'my' record it is fair to say that in real time here is my current position, my current organizational unit, my current job and if the status is correct this is all in 'real' time.
Does this answer your question or do you now have a follow-up question?
