If the sales ledger account that the credit is being raised against is set as a cash account the ‘Cash Payments’ window will show.
From the ‘Type’ drop down menu select the payment method. i.e. Cash, Card or Cheque, then select the ‘Add Payment’ button, this will move the payment to the upper part of the screen.
If the incorrect payment method is selected click the 
icon to remove the payment line. Select ‘Accept’ to confirm the payment.
