Short Answer: That message means 'Unexplained difference' is non-zero. You may still submit or certify, but the unexplained difference will remain visible in the reconciliation.
PreRequisites
- An account with a non-zero Unexplained difference.
Steps
-
Open the account detail and check 'Difference' and 'Unexplained difference'. You can see the amount flagged in red and the explanation message.
-
To reduce the unexplained difference, add supporting items via '+ Add supporting item' or 'Upload file' in the Supporting items area. Supported balance increases and Unexplained difference reduces if amounts match.
-
If you choose not to resolve it, you can proceed: in 'Submit for review?' click 'Submit anyway' or as Reviewer click 'Certify' → 'Certify anyway'. The account moves to 'Awaiting review' or becomes 'Certified' while the unexplained difference remains visible.
Troubleshooting
-
Unexplained difference remains unchanged after adding items.
LikelyCause: Effect (Add/Reduce) selected incorrectly or incorrect amounts were entered.
Action: Edit or remove the supporting item and re-add it with the correct 'Effect on supported balance' and amount sign. -
I still see the warning in the submit/certify modal.
LikelyCause: Unexplained difference was not fully resolved.
Action: Either resolve the remaining difference or proceed with 'Submit anyway' / 'Certify anyway' knowing the difference will be shown in the reconciliation.
Note: The product shows an explicit warning in the confirmation modals; proceed only if you accept that the unexplained amount will remain visible.
