I have a figure on my balance sheet. When I look at the account that figure is what shows for my ending balance, however, there is no detail. I have gone backwards with my date and no detail. It is not in Future Dated Transactions. How can I find out what this figure is from?

If it's not in your current file then it could be due to transactions in prior years that could have been deleted on rollover.

Another possibility is it's an opening balance entered through set-up, balances, account opening balances.
