Can not find a table in DBA_TAB_PRIVS and ROLE_TAB_PRIVS

Question

I get a table 'KNA1', a table of SAP R3 ERP application, and tried to find out all privileges granted to 'KNA1'. Using the SQL statement below, I am sure 'KNA1' is existing.
SQL> SELECT * FROM DBA_OBJECTS WHERE OBJECT_NAME = 'KNA1';
OWNER
OBJECT_NAME
SUBOBJECT_NAME OBJECT_ID DATA_OBJECT_ID OBJECT_TYPE
CREATED LAST_DDL_ TIMESTAMP STATUS T G S
SAPR3
KNA1
7480 7480 TABLE
30-JUL-02 30-JUL-02 2002-07-30:15:26:22 VALID N N N
However, when I tried to find 'KNA1' in 'DBA_TAB_PRIVS' and 'ROLE_TAB_PRIVS', the result is 'no rows selected'.
SQL> SELECT * FROM SYS.DBA_TAB_PRIVS WHERE TABLE_NAME = 'KNA1';
no rows selected
SQL> SELECT * FROM ROLE_TAB_PRIVS WHERE TABLE_NAME = 'KNA1';
no rows selected
SQL> SELECT * FROM SYS.ROLE_TAB_PRIVS WHERE TABLE_NAME = 'KNA1';
no rows selected
Dose that answer mean 'KNA1' did not be granted to any user or role?
If it is true, why can I still use KNA1 wtihout any problem?
If it is not true, where can I find the privileges information related to 'KNA1'?
Thanks a lot.
