Restricting team viewer in MSS

Hi Experts,

We are trying to restrict the list of employees available in the team viewer in MSS based on whether they are on a full-time salary or not.

I can't see any user-exits or BADIs which we can use so has anyone any ideas?

Cheers,

Russ.

NB. I have set breakpoints in HRWPC_RFC_OADP_GET_OBJECTS and HRWPC_RFC_PERSONALDATA_GETLIST and chopped the t_pernr tables down from 10 entries to 8 entries. However 10 still get displayed.in Team Viewer.
