Currently, there is a problem with fixed-price project estimates i.e., booking full invoice amount to revenues if there was an advance invoice as well, on the project. If the project is complete, 100% estimate needs to be done so that the full invoice amount is booked to revenues. However, because of the advance invoice, and with the final invoice having been issued, the estimate reduces the contract value to the full amount less the advance amount. In summary, the system wants to reduce the revenues (by the advance amount) instead of increasing it to the full amount (adding back the advance) in the case of a fixed price, advance invoice scenario
