When you create a new prediction, the accounts impacted section shows the journal movements that the prediction creates.
The accounts shown depend on:
The account you select for the prediction
The default bank account set in the forecast settings
The default VAT/GST/Sales tax account set in the forecast settings
The Accounts Receivable or Accounts Payable account, if the prediction includes payment terms
The balancing account, if you create a non-cash transfer
As you update the prediction, the Accounts impacted section updates automatically to show how the journal movements affect each account.
