Hi

Acknowledgments can be used only together with Async. messages.

In sync. messages there is no need for acknowledgements, as you always get an error or a response message, so the sender of the message always knows, if the message was sent successfully or not.

<b>System acknowledgments</b> used by the runtime environment to confirm that an asynchronous message has reached the receiver. for e.g in File Adapter, if ftp server is up and running/or Folder name exists etc

<b>Application acknowledgments</b> used to confirm that the asynchronous message has been successfully processed at the receiver. from SAP help.

Hey

An acknowledgment replies to an asynchronous request message in order to inform thesender about the status of the message processing. There are four different types of acknowledgments:

<b>System acknowledgment:</b> Sent back when the request message arrives at thefinal receiver.

<b>System error acknowledgment:</b> Sent back when a system error occurs duringmessage processing within SAP XI.

<b>Application acknowledgment:</b> Sent back when the request message is

successfully processed within the receiver application.

<b>Application error acknowledgment:</b> Sent back when an error occurs during

message processing within the receiver application.

Hi,

System acknowledgments used by the runtime environment to confirm that an asynchronous message has reached the receiver.

Application acknowledgments used to confirm that the asynchronous message has been successfully processed at the receiver.

For more about acknowledgments go through this SAP help file which dictates about it:

See one example of acknowledgments:
