trial balance - how to find mismatch question

I just noticed the subject was wrong due to a user-digest error, re-applying the original.

I’m having a bit of issue understanding the point of the trial-balance report in modern times. (I generally don’t use it as I mentioned)

If each transaction self-balances, that is, debits = credits, how is it possible to add up the debits individually and the credits individually and not get a result that still balances? You can’t add up 1+2+3 = 5 and 1+2+3 = 6. It’s a mathematical impossibility.

In addition, if you enter a transaction that doesn’t balance, Gnucash forces it to balance by using either the imbalance or orphan accounts. So at least you’re alerted to amounts you need to fix, but technically, debits still equal credits.

Let’s assume I entered a transaction backwards and debited my cash account instead of crediting it, and credited an expense account instead of debiting it. This should not affect the trial-balance. Sure, the amounts are wrong for each account, but they still balance. Debits still equal credits.

If I transpose two digits (the divisible by ‘9’ trick) then as long as my individual transaction I did this in balances, it still shouldn’t show up as an imbalance on the trial-balance report. The other side would ALSO have to be transposed or incorrect to match it. Gnucash won’t save the transaction unless it’s balanced.

I can’t see what possible error could produce individually balanced transactions (required by Gnucash) and yet still have a trial-balance where the debits do not equal credits AND both the imbalance account and orphan accounts are empty.

(note, I understand why this report is run with paper records because you’re copying stuff all over the place and might do so incorrectly. But this isn’t the case with Gnucash)

Adrien

(maybe even a day before and after just to be thorough) Also be sure to check all boxes on the Status tab in the Filter options. You want to see all transactions for that date range. Then just look over them and see if anything looks out of place. In particular, look for either the amount you are out of balance by or half that amount if the variance is an even number. (meaning you have an entry that is entered in reverse debit/credit, or entirely duplicated)

I recall doing some re-organization and I went through a series of unposting paid invoices and reposting them, causing my lot assignments to get out of whack. I know I have some open lots that shouldn’t be there and many that are applied to the wrong documents. I’ll clean that up first, then re-run the trial balance and see if that does the trick. I’m not sure where the Trial-Balance report is pulling its numbers from, but it won’t hurt to perform that cleanup anyway.

Keep doing this till you get a balance, then set that ending date to a new start date, and start working forwards till you get out of balance again. This will help you narrow down where on the calendar the error occurred.

>> OK - did that and ran into something VERY strange.  Everything stayed in balance up to 07/12/2016.  Setting that as the start date and 12/31/2016 as the end date, as soon as I hit "apply", QC overwrites the end date with - get this - 02/27/1899 !!!  This of course produces nonsense.  One day later (01/01/2017) works fine and shows the imbalance.  So, have I 1) found a bug, and 2) given I have narrowed the date range to a few weeks, what report should I run to find the weirdness? - Elmar
