ABAP Proxy - trace

jakob_steen-petersen — Wed, 11 Apr 2012 10:34:02 GMT

I´m using an ABAP Proxy to consume a webservice. The Webservice does not return the correct data, so i need to send the actual raw XML to the Webservice developer.

But where can i find the actual XML of the call (and the response)?

We are NOT using SAP PI - the Webservice is called directly from AS ABAP.

Check transaction SXMB_MONI if you can find your proxy XML messages. Ideally you should be able to find them in processed XML messages. Double click on message and check payload from actual XML message which was transmitted.

SXMB_MONI is empty. No messages are shown in this transaction on the AS ABAP system.

But i´m sure that i have called the service and got response...

Hi Jakob,

The default trace level in SXMB_MONI for synchronous services is to only display a message in the event of an error (space reasons I assume). Talk to your BASIS guys about making sure the trace level is extended to all messages - we have done this in our development system for unit testing purposes.

Well in this case i am "the basis guy"... But i cannot find anything about that parameter. I have set parameter Runtime/trace_level = 3 in T-code SXMB_ADM - but this did´nt do the trick.

Do you know which parameter to change?

Try testing it through SE80 by entering your class name and method name.

Hi Jakob,

One of the BASIS guys here says it's the parameter LOGGING_SYNC under the RUNTIME category.

Yes i have tried that parameter - and normally in an PI environment i would expect it to work. But it seems to me that nothing is stored in the SXMB_XXX transactions at all. If i call the statistics overview it´s also empty.

Ryan-Crosby — Wed, 11 Apr 2012 17:56:58 GMT

Hi Jakob,

I would check how this ABAP Proxy is executed then because I just checked this in our R/3 development environment where we call an outside web service and I had an entry for both the outbound and inbound message show in SXMB_MONI.

Ryan Crosby

I could have done it totally wrong, but the way i´m using the proxy is:

1. Generating client proxy in SE80 using wsdl

2. Setting up a logical port using LPCONFIG. The port points to an HTTP destination (defined in SM59)

3. Using the Class in a simpleABAP program.

Its working fine with another service on the same system - but still i cannot see anything in SXMB_MONI. It´s seems to me that the "XI" part of my AS ABAP is not used at all?

Re: ABAP Proxy - trace

Ryan-Crosby — Wed, 11 Apr 2012 18:12:17 GMT

Hi Jakob,

I imagine the source code for the ABAP program is rather small? Can you include it so I can see how you are calling the proxy?

Hi,

Now I see the issue... since you are executing it directly without an interface that is defined from a PI or XI system (you'd see the method EXECUTE_SYNCHRONOUS) it's not going to run on the integration engine where you would get the log in SXMB_MONI.

Regards,

Ryan Crosby

jakob_steen-petersen — Wed, 11 Apr 2012 18:44:43 GMT

Yes exactly - as i wrote in the first post: "We are NOT using SAP PI - the Webservice is called directly from AS ABAP"

There is no integration engine involved at all...

Re: ABAP Proxy - trace

jakob_steen-petersen — Wed, 11 Apr 2012 18:47:35 GMT

Yes could be an idea - but i have one simple problem: the Testtool cannot start up because i´m on an Citrix enviroment who currently cannot start the New ABAP editor..

Silly problem - but a fact

Also i´m not sure if i can pass the Security header in the Testtool of SE80?

Re: ABAP Proxy - trace

Ryan-Crosby — Wed, 11 Apr 2012 18:51:58 GMT

I skimmed the overall gist and saw reference to SXMB_MONI so I missed some of the particulars for your problem
