The following post can be used to create a Cash receipt in Oracle Receivables. The “ar_receipt_api_pub.create_cash” SQL API is used to create cash receipts for the payment received in the form of a check or cash. Cash receipts can be created as identified (with a customer) or as unidentified (without a customer).
