As a user, I would like the behavior of the NvRb button to be consistent across both DA and non-DA rebillable expenses.
Currently, for a non-DA rebillable expense, the NvRb function only works when part of the rebillable expense has been rebilled. When you click NvRb for non-DA rebillable expenses that have not been rebilled at all, the entire rebill balance is still reflected in the P&L.
(To compare, when you click NvRb on a rebillable item from a DA which has not been rebilled at all, the entire amount is removed from the Rebills section of the P&L.)
I’d like the NvRb button to have the same effect on non-DA rebillable expenses that have not been rebilled.
