Track external messages in XI and SAP

Question

Hi XI guys.
I have following question: external system wants to get application acknowledgements from SAP and XI that particular document has been posted successfully in SAP.
It is going to assign Unique number to every XML message and wants response back (not synchronous because we are using IDOCs) with this Unique ID.
Is there easy standard way to do it without actually storing this unique ID in SAP (storing it may not be possible for all situations) ?

Answer 1

Hi,
The prequsites to be done in XI and SAP system for idoc transfer from XI to SAP or vice versa?
Initially RFC destinations to be created in XI system pointing to R/3 and in R/3 system pointing to XI.
Outgoing IDOC from R/3     (R/3 Side Config)
WE21 create a port & while creating it give the RFC destination which point to the XI system.
WE20 Create a partner profile in partner KU (for outgoing). The partner number you give here should already be defined in R/3 with partner type KU. In the outbound parameters of this newly created partner profile, Enter the port number created in step 1 for Receiver port, Message type, Partner role, Basic IDOC type all in the Output options tab.
Then in the Message Control tab you need to enter the Application, Message type & Process Code. You have F4 help for all of these.
In BD54 RFC destination name has to be defined as the logical system name (Logical system Name or RFC destination name – always keep it 10 chars or you might face a problem in SLD inside XI.
Finally if your scenario demands that an IDOC is automatically created when you save a transaction then in the output parameters of that transaction you need to select EDI as the output parameter.
(XI Side Config)
6.     IDX1 create a port & while creating it give the RFC destination which point to the R/3 system.
7.     IDX2 for the port created in step 6, load the IDOC metadata from the R/3 client which is sending the IDOC to XI.
Hope this helps.
Regards.
