Accounts Receivables "Outstanding" balance not matching Trial balance

Hello everyone, I have a situation where at any point in time, the Outstanding balance on my Accounts Receivable report is not tallying with the Receivables on the Trial balance. To be specific, as 31 Dec, 2022 the receivable report is at 337, 000 but for the same 2022 period, the Debtors Account is showing only 109, 000.
Any idea what I could be missing? Thanks in advance.

You need to manually investigate this. Pull AR and find the matching invoice. There’s some error in your invoicing or maybe somehow manual incorrect entries were passed.

Thank you very much!
