(Delphi ActiveX) Walmart v3 Acknowledge Orders

Allows a DSV to acknowledge an order, including all order lines, preferably within four hours of receipt of the order.

The response to a successful call contains the acknowledged order. As a good practice, acknowledge your orders to avoid underselling.

Note: This example requires Chilkat v9.5.0.85 or greater.
