Void grant

Voiding a grant means it is no longer valid, it doesn't take part in further balance calculations. Voiding a grant does not retroactively take effect, meaning any usage that has already been attributed to the grant will remain, but future usage cannot be burnt down from the grant. For example, if you have a single grant for your metered entitlement with an initial amount of 100, and so far 60 usage has been metered, the grant (and the entitlement itself) would have a balance of 40. If you then void that grant, balance becomes 0, but the 60 previous usage will not be affected.
