Create message for HTTP receiver to send Acknowledgments

[former_member84192]

I have the follwoing scenario

R/3 Purchase Order IDOC sender ---> PI 70 ---> HTTP receiver external vendor system

What it does it sends an ORDERS IDOC from R/3 to XI and in XI the IDOC is transformed to an XML sent with PlainHTTP to the vendor system. In design I am using:

1) XCBL standard XSD schemas for PurchaseOrder message types and interface (that the Vendor provided me with)

2) Some old SAP XSLT mapping programs I found from the Business Connector era, that do exactly that convert R/3 IDOC to the standard XCBL Order.

All this works fine. What I want to do now, is get a system acknowledgment from the vendor system that they have received the message. I know that this can't be done in terms of XI acknowledgments (at least not without BPM).

But the vendor partner has also provided me with another standard XSD for MessageAcknowledgments and he has also given me an example of what his response message would look like. They have implemented this with another customer of theirs that uses XI and I would like to do the same, only I don't know how.

The vendor response (based on the XCBL standard XSD) looks like this and has three fields. The first and third are obviously populated from the PurcheseOrder XML received by the vendor him and the second field looks like the message ID of the XI system that sent him the PurchaseOrder

<MessageAcknowledgement>

<AcknowledgementLocation>Other</AcknowledgementLocation>

<AcknowledgementReferenceNumber>01ddb5c6-7a75-1000-a53c-0a1006170001</AcknowledgementReferenceNumber>

<AcknowledgementNote>Date:20090614T12:00:00+01:00 DocType:Order DocNum:4550195032 Originator:265755319</AcknowledgementNote>

</MessageAcknowledgement>

I would appreciate any jumpstart ideas on how to go about this.

2) APPLICATION ACKNOWLEDGMENT

A message in the form of OrderResponse XSD standard that will be converted by XI to an ORDRSP IDOC that will be posted to the ERP backend and update Purchase Order confirmationd etails in MM

Hi Lukas!

I think you have 2 scenarios indeed.

First scenario would be an BPM, as you've got an async/sync communication.

IDOC(async)->Http(sync). i guess you need the response from Http (message ack) to do something with it.

The second scenario you can do it without BPM if you don't need to answer with an ack either.

HTTP(async)->IDOC(async)
