How to map explain plan and predicate information to get exact SQL code line number?

How to map explain plan and predicate information to get exact SQL code line number?

Example:

From below explain plan, the operation at line number 309 is doing a full table scan on 48million row table. And, the predicate information section displays (access(:Z>=:Z AND :Z<=:Z)) for the explain plan line number. The SQL code is very lenghty (more than 2000 lines and referencing some views which too has > 2000 lines). How can I spot the exact line in the SQL code which is fulfilling the operation?

Plan hash value: 2785661414
