Fw: tables with no synonyms

Assuming I've understood the question correctly, you can just take the objects 
(including program units) that are owned by user A, and subtract (MINUS) the 
synonyms owned by B that reference those objects in A. 
 
select object_name, owner from dba_objects where owner = 'A'
minus
select table_name,table_owner from dba_synonyms where owner = 'B'
/
