Given accounts: Asset: Bank checking Reconciled to date 11/01/23 Liability: car note not reconciled Expense: other-expenses The bank checking account is reconciled with some transactions going to other-expenses. However, one of the transactions was intended go towards the liabilities. When user is reconciling the Liabilities account, they may noticed that the transaction for the car note is missing. If they try to enter the transaction, KmyMoney will not complain even if they enter the new transaction for 10/15/2023. STEPS TO REPRODUCE 1. Create a checking account, liability and expense account. 2. reconcile the checking account to date 3. Enter a new transaction in the Liability account that will affect the checking account prior to the date of reconciliation. OBSERVED RESULT KMyMoney does not warn the user. EXPECTED RESULT KMyMoney should warn the user that the entering the transaction will cause a reconciled time period on the partner account to no longer be reconciled. KMyMoney should then un-reconcile the checking account as of the date of the new transaction.
