Apply security on object Prompt

Hi All,

Need to apply security on prompt used in webi report.

Here is the requirement.

prompt has two LOV (Y OR N)

There are two users user1 & user2 both users have access to report.

when I login with user1 and access the report and select LOV as Y data should be displayed

When I login with user2 and access the report and select LOV as Y data should not display

please let me know how can we achieve this ?

Regards,

Raj
