Lost portion of last year's customers' transactions record in A/R. Our year end is April 30, I didn't choose to clear the history when closing year end in A/R, currently go to each customer/transaction, there is the history record before Nov.25, year end outstanding and then all new fiscal year's transactions, all history record from Dec. to April disappeared!

only in A/R, the history record in A/P is ok. How it happened? Can I get those record back? Thanks in advance!!
