Nominal accounts need to be set as Bank or Petty Cash type in their nominal record for them to show in the Cashbook. This can be done as follows:
In Financials, Accounts, find and open the nominal account to be set.
Select the Details tab and click Edit.
Toggle the Account Type to the required one and Save.
Please note that any transactions posted to the account before it is set as Bank or Petty Cash type will not appear for reconciliation. For further assistance with this, please raise a new case online and reference the title of this article.
