I posted another beginning balance with same negative amount and it is impacted the project statement. When I go to the Common > Transactions > Posted transactions >> Select the reversal transaction >> Click View ledger updates. The "amount" field is showing as positive amount instead of negative amount. Can any one please explain if I can ignore the "amount" value in “ledger update”?
