System Acknowledgement to SOAP request

[Former Member]

Hello All,

While working on the following scenario SOAP -> XI -> ABAP Proxy, I need a system acknowledgement to be send back to the requesting system. I had few queries on the same.

1. Currently in SXMB_MONI, I see the Ack. Status as blank. Does this mean that the server has not been setup for receiving acknowledgements?

2. I did a lot of reading on the blogs and every where I find that that sender system needs to request for an acknowledgement. How do I get my SOAP message (or SOAP adapter) to request and acknowledgement?

Kindly help,

Thanks and Regards,

Keerti

Thanks Sai,

Unfortunately our implementation doesnt include a Java proxy. Its a simple web service that is been exposed.

Keerti,

I tried to follow your method of using element 'ReliableMessaging' generating Acknowledgement in SOAP client and it does generate acknowledgement in PI system, but i am not sure how to receive that acknowledgement in my SOAP client.

my SOAP client is a simple Javascript code that uses XMLHTTP POST.

What I want to do is to

1) constuct a SOAP message header using element 'ReliableMessaging' to generate Acknowledgement id for Async message in PI

2) capture Ack id in SOAP client before client executin is completed

3) later create another SOAP client to query status of Acknowledgement id received in Step 2

I have able to do step 1) per your method, but unsure how to write/extend SOAP client to perform step 2) & 3).

I will appreciate any pointers,

After much research, I tried doing the following and it worked for me:

Step 1:

To do that, the SOAP request message must contain an additional tag in the request:

<SOAP:Envelope …>

<SOAP:Header>

<SAP:ReliableMessaging SystemAckRequested="false" SystemErrorAckRequested="true" ApplicationAckRequested="false" ApplicationErrorAckRequested="false" SOAP:mustUnderstand="1">

<SAP:QualityOfService>ExactlyOnce</SAP:QualityOfService>

</SAP:ReliableMessaging>

</SOAP:Header>

</SOAP:Envelope>

Step 2:

In the SOAP communication channel, turn on the Conversion Parameters > Keep Header.

If anyone has any better ideas, please keep me posted on it.
