This article explains how to void an 'AR' type cash receipt in Cashbook Bank Management using Microsoft Dynamics GP. The cash receipt is listed in the Build Deposits Entry window in Cashbook Management and there is no way to delete it in this window. If you deposit it in Cashbook Management and then try to delete this deposit in the Transaction Enquiry/Void window, you will get the message:
This deposit is an AR transaction and cannot be voided from the Bank Recon.
