The resource assessment phase comprises of two distinct steps:
- Resource Assessment Pre - in this phase, accounting systems are sequentially called to perform assessments of account balances before the Order / Distribution phases. This updates the accounting system balances so that Account Hosts are able to get accurate resource assessment information before fulfilling orders.
- Resource Assessment Post - This phase is called after flow distribution and gives the accounting system access to the post ordering state of the system. It is within this phase that shortfalls from Order use systems can be re-credited to accounts, as well as performing actions such as crediting carry-over before writing off accounts at the end of the water year.
