PeopleSoft Expenses - Travel Authorization and Accounts Payable Budget Checking

I am trying to implement the Expenses module for my client. Instead of the delivered Pay Cycle to pay the Expense transactions, they want to create vouchers in Accounts Payable instead to process the payments from Expenses.

They also want to budget check during the Travel Authorization process to create encumbrances that the Accounts Payable would then liquidate once the corresponding voucher is created and budget checked. My question is will the budget checking process on the Accounts Payable side liquidate the encumbrance that was created on the Travel Authorization side as long as it has the same chartfields?

Thanks.
