If you are using a saved search within Access Financials, then this issue can be caused by a recent update to the screen.
To correct this, remove the saved search and re-create it. This may clear the error.
Clear all browser cache and cookie settings, and then close/reopen the web browser to log back into Access Financials, which should resolve the issue.
To save time, copy and paste from a spreadsheet into the import grid (Debtors, Utilities, Imports, Sales Transactions Grid).
If the above is unsuccessful try the below:
Close the Financials tab, and reopen it from the nine dot menu
Close the Financials tab, log out of Workspace, and then log back in a new browser tab.
