e-ADK 3.9 provides the ability to set acknowledgement of messages. This feature provides verification of the status of messages that are sent to transports using Acquire and Process modes. The acknowledgement is sent both when the message is successful (ack) and unsuccessful (nack).
In some cases, an adapter might need to take a specific action only if the message was successfully received by the transport. If the message fails, another action is required. For example, when an order is placed online, information needs to be sent to a purchase order transport. If the message is successfully sent to the transport, then an inventory action takes place. If the message fails on the purchase order transport, an alert action is produced. In this case, if the e-ARE sends an acknowledgement (ack), then the inventory action takes place. If the e-ARE sends a negative acknowledgement (nack), the alert action takes place.
