Without screen shot its hard to know exactly what you are trying to hide from where….
But , I’m guess it is the D.O.B from the short profile element of the employee profile. If so try this:
IMG: Personnel Management -> Manager Self Service (WDA) -> Profile Applications ->General Settings -> Configure Short Profile -> Configuration for Data Reterval -> Create Configuration with field groups.
- Select the row SAP_MSS_GENERAL_PROFILE (or SAP_MSS_GENPROFILE_SHORT)
- With the row selected, navigate to the Add fields to a configuration
- Remove the row for field SAP_PS_BIRTHDATE
