Identifying Radio Columns in Radio Group for Authorization

Question

Hi friends,
I have a single radio group page item which has a 3 no.of columns. I have defined a static lov definition for it as it shows three values for the three column in a single radio group page item. These are the values.
<li> Self
<li> On behalf of
<li> New Hire
I need to restrict these three values according to the user roles. For that i can write an authorization and take the users corresponding to their roles.
But how i can refer this authorization according to the values that radio group has. Since that radio button is a single page item.
I need to restrict the three values of the radio button to the three set of users under the specific roles.
I wrote the three sets of authorization which is filtering the three set of role users, accordingly to their login in the application. But how to refer these three authorization rules to a single radio group page item.
If it is a single authorization means, i can refer it to that radio group page item under the security section.
How to refer these three sets of authorization to a single radio group page item.

Answer 1

Write a PL/SQL authorization function that returns a Boolean or a Y/N based on knowing the role and the radio group item. Pass in the Role and the Radio Group select item.
Write an LOV for the Radio Group which is a query that adds the Radio Group item if the authorization passes and does not include it if the authorization fails
ie.
SELECT 'Self' FROM DUAL WHERE SECURITY_PKG.Role_has_auth(role_name, 'SELF') = 'Y'
UNION ALL
SELECT 'On Behalf of' FROM DUAL WHERE SECURITY_PKG.Role_has_auth(role_name, 'ON BEHALF OF') = 'Y'
UNION ALL
SELECT 'New Hire' FROM DUAL WHERE SECURITY_PKG.Role_has_auth(role_name, 'NEW HIRE') = 'Y'
