Contracts

A closed amount on a contract in the prior year cannot be used again. It Liquidates that amount from the contract and cannot become available money again.

• This is by design
• In the future, it's advised to roll the contract or create a change order reducing the contract amount if those monies need to potentially be used in the next year
