First, run the Creditor Balance By Period for the same period or year, preferably to Excel.
If this matches the aged creditors report, then the trial balance is incorrect and so we suggest searching for non-purchase-based postings, such as journals (J) and nominal disbursements (ND).
However, if it matches the trial balance, then compare the two creditor reports in Excel, to enable you to find the specific accounts the imbalance relates to.
Upon determining whether the trial balance or aged creditors report is incorrect, if it is postings like Journals or incorrect posting types in the nominal these will need correcting by you to add them to the correct nominal.
If the imbalance can't be corrected by you please raise a new case online and reference the title of this article
