Hi again Audrey,
Yes it could work out that way, but I don't have a clear view on your exact requirement.
Do any of these users need access to anyone else's IT0008? Or do they only need to see their own?
In that case, a combination of P_ORGIN and P_PERNR would do the trick.
I'm sure if you provide a more precise description of what exactly your requirement is, maybe with a screenshot of what you currently have, we can find a workable solution for it.
Good luck!
Dimitri.
