Currently, POS users have no way of knowing from the front end if HO has allowed them to change particular policies like applicable discount amount / rates. The Modify rights of Master Policy Management only shows that the users assigned to the particular role can modify the Master Policy values, that the HO permits to change. But it does not show which rights are allowed to be modified. So, in case any POS user (of a non-centralized POS) needs to change a Master Policy value, they might have to go through trial and error, which is frustrating for the user. But if there was an opportunity to view the same in read-only mode from the POS Administration module > Policy > Master Policy > User Settings OR POS Administration module > Security > Roles > Access Rights, it would be easier for the users.
Small idea, but may prove to be useful for POS Administrators.
