acquire auth object related to a specific TCODE

How can we Retrive the auth object which is related a specific TCODE?
As far as now, i got three ways:
1. TCODE: ST01, trace the authorization
2. TCODE: SU24
3. From the table USOBT(Relation transaction > authorization object)
table TSTCA(Values for transaction code authorizations)
