Summary
When for example rename a table or add a new column to the table the objects (procedures, packages, triggers etc) what references the table get invalid. To find which objects have a reference to table HELPDESK.S_RECIPIENTS execute:

SELECT D.owner, NAME, TYPE, O.LAST_DDL_TIME, O.status, DEPENDENCY_TYPE 
FROM all_dependencies D, dba_objects O
WHERE O.OBJECT_NAME = D.NAME 
AND O.OWNER = D.OWNER 
AND referenced_owner = 'HELPDESK' 
AND referenced_name = 'S_RECIPIENTS';

All dependencies are in the view: ALL_DEPENDENCIES

Column               Description
------               -----------
OWNER                Owner of the object

TYPE                 Type of object
REFERENCED_OWNER     Owner of the parent object
REFERENCED_NAME      Type of parent object
REFERENCED_TYPE      Type of referenced object
REFERENCED_LINK_NAME Name of the link to the parent object (if remote)
SCHEMAID             ID of the current schema
DEPENDENCY_TYPE      Whether the dependency is a REF dependency (REF) or not (HARD)

            START WITH dep.referenced_object_id = obj.object_id
            ORDER SIBLINGS BY dep.object_id DESC) dep
 WHERE dep.object_id = obj.object_id;
