ESS Maintain own data only

Question

Hi Expert,
  Any switch to enable ESS user to display his/her own data?
My requirment is that user should be able to view his/her own data but not data of other.
We have defined communication 105 with a corresponding id.
If we grant permission on infotype 8 to that user id
That user would be able to not only view his/her own data but also everyone's data (of course we have grant access to PA20).
Is there any way to control he/she can only acces own data.

Lewis,
Although the structural authorization example will work, there's a simpler way.  For the ESS users, you must assign the authorization object P_PERNR for the infotypes (and subtypes) and that you want them to see only their own data for, and make sure you do not assign them P_ORGIN for those infotypes.
Before P_PERNR is effective, though, you must activate the authorization check for this object.  You do this with transaction OOAC, changing the value for AUTSW PERNR to 1.
P_PERNR comes into play when a user tries to access infotype data against their own personnel number.  For other personnel numbers, P_ORGIN is used.
