SUMMARY I paid commission in USD when bought some US stocks. My base currency and the currency of the investment account is HUF. In the reports (Transactions by Accounts and Transactions by Categories) the commission showing incorrect amounts (e.g. 711927.31 HUF for $7.99 -> 89102.2916 HUF/USD). When checking Commission category e.g. in Income and Expenses This Year report or by double clicking it in the Categories view to open in Ledger view, the correct amount shown (2389.90 HUF for $7.99 -> 299.1113 HUF/USD). Correct amount can be calculated in Transactions by Accounts report too: total amount in the "[Split Transaction]" line and the total price paid in "Transfer to: Investments: Investment account: Stock" are correct so commission can be calculated, though showing the wrong amount. STEPS TO REPRODUCE 1. Book the investment transaction 2. Fill the correct amount or exchange rate in the popup window 3. Check Transactions... reports OBSERVED RESULT Amount of commission in base currency is wrong in Transactions reports of Reports view, correct in Income and Expenses and Cash flow reports of Reports view and also correct in Categories view (Ledger view). EXPECTED RESULT Reports show the same amount as one can see in Categories. SOFTWARE/OS VERSIONS Windows: Windows 10 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: 5.71.0 Qt Version: 5.15.0 ADDITIONAL INFORMATION I use the last stable build of KMYMoney for Windows 5.1-763.
