Issue in structural authorization

Hi Gurus,

Good day.

We have an issue on Structural Authorization.

Our setup:

In Tcode OOSP

Auth. Profile               No     Plan Vers.          Obj. Type          Object I          Maint          Eval Path          Status vec

ZHRLINE100               5          1                         O                   100000               X          O-O_DOWN               12

ISSUE: There's a staff (ie pernr 100) under an OU (ie 100020) that is also under the main OU 100000 that they dont want to display.

Since all the profiles are using the above setup in OOSP they were able to see in PA20 staff 100.

Is there a way in Structural authorization to prevent all line managers from seeing the record of staff 100?

Thanks.

Cris
