Updating Customer History
In the Accounts Receivable Payments tab, check the Update Customer History box. If you do not want to update the customer's history, leave this box blank.
The customer's history information is updated with the payment date, check number, and amount when the payments are posted. This information is displayed in the Last Payment boxes in the Accounts Receivable Post/Change tab.
Note: Generally, you should update this information. Occasions when you do not want to update check information include using a check to make adjustments to an account, or making adjustments to a check register.
