Roles and permissions

thank you for replay
i had check it its access.php is wright
but
there is no record in role_capabilities table of report.

my /gade/report/mynewreport/db/access.php is

<?php
$gradereport_mynewreport_capabilities = array(
'gradereport/mynewreport:view' => array(
'riskbitmask' => RISK_PERSONAL,
'captype' => 'read',
'contextlevel' => CONTEXT_COURSE,
'legacy' => array(
'student' => CAP_ALLOW,
'teacher' => CAP_ALLOW,
'editingteacher' => CAP_ALLOW,
'admin' => CAP_ALLOW
)
)
);
?>

and role_capabilities table records are as follow:

query that i use.

mysql> select id,roleid,capability from mdl_role_capabilities where capability like 'graderep%';

result of query is:

+-----+--------+---------------------------+
| id | roleid | capability |
+-----+--------+---------------------------+
