V_T7XSSPERSUBTY doesnot show read-only check box

Hi,

  The view V_T7XSSPERSUBTY is not showing the check box to make the subtype read only. I want the entire bank details and personnel information screen to be in read only mode. In personnel information i should be able to change the photo, and the rest has to be in read only mode.

Is this possible in customizing, or i have to make use of the BADI HRXSS_PER_SUBTYPE. We are using EHP 5.

Regards

Govind
