Transactions Set in stone ?

Re: the Account Balance Breakdown Report - a bit of a mouthfull lol

On running this it shows as the report name suggests a complete breakdown of payments to go out on the next installment day -

This report is divided into subsections , the

Transactions to be paid in next payment i believe - correct me if i wrong - details the transactions that have already been cleared ie: paid to TD

Are these payments set in stone , or can they be reversed ? the reason i am asking is i would like to pay a cashback customer in advance of the payment day nut as it is a largish amount i don't want to take any chances .

OK thanks for any explaination .
