I was doing bank reconciliation in June, there was a voided cheque on our book, it has been cashed out from bank, i did an adjustment (add/subtract bank error) on the bank reconciliation sheet to balance it, didn't touch our book, in July, bank refunded to us for the voided cheque amount, once we received the refund, i did an journal entry in our book to record it, i think all it's correct, since then, the bank reconciliation hasn't been balanced in two months, the variance amount is the refunded amount, but last week, when i was doing the September reconciliation, the variance was disappeared, it's balanced, i am confused now, why the variance stay there for two months, then in September disappeared, is there something wrong? can anyone please help me on this? or give me a clue how to check on this?
