Typically, if you have an imbalance on either your Nominal Viewer or Trial balance report then you'll want to ensure all accounts are linked to the nominal viewer structure. To check if you have any unlinked nominal accounts:
In the toolbar, click Nominal Ledger.
Click Nominal Accounts (or Accounts).
Set the Only Unlinked Accounts filter to Yes.
If any unlinked accounts appear, link them. See the article on linking a nominal account to Profit & Loss or Balance Sheet.
If an imbalance remains after linking all accounts, narrow down the period where it exists:
In the toolbar, click Nominal Ledger.
Click Nominal Viewer.
Change Balances For to Period.
Enter a Year and Period and check whether the imbalance exists there.
Repeat for different periods until you identify where the imbalance starts.
Once you identify the period, check for unbalanced folio postings:
In the toolbar, click Nominal Ledger.
Click Reports.
Click the Unbalanced folio listings report.
Enter the Year and Period identified above.
If an unbalanced folio posting accounts for the difference, balance it by posting a one-sided journal. See the article on how to post a one-sided journal. If no unbalanced folio posting is found, continue with the Ledger Reconciliation report:
In the toolbar, click Nominal Ledger.
Click Reports.
Click the Ledger Reconciliation report.
Enter the Year and Period identified above.
If the report shows a difference between the Ledger and the Nominal Control, contact support to have the Ledger Balances rebuilt.
If none of the above identifies the imbalance, contact support. A nominal entry may have been written to a nominal account that does not exist. See Get support in Dimensions and reference this article.
