Lets assume your developer selects from a particular table and you want to delimit that, based on one field of that table. One possible approach could be:
1. start se11, display the table from which you want to select. (example: table FICOC_COND_AMT)
2. identify the field you want to be checked.(example FICOC_COND_AMT-O_CONDTYPE)
3.check the corresponding Data element for that field in se11 (example for O_CONDTYPE it's FICO_OCONDTYPE)
4.with that Data element select from table authx, enter the data element into selection field 'ROLLNAME'
5. with a bit of luck you will find 1 or more authorization fields defined by this data element.
6. the rest is easy.... display the field(s) in su20->on the bottom of the auth-field display-screen you have the authorization object(s) which contain that field
