Hi there SAP fans,

one of my partners wants to use the asynchron protocol. Of course the regular workflow of an optimization call returns a proper result with a HTTP-200 status code.

The asynch process requires a user to call the fetchXXX-operation once the status of a Job is SUCCEEDED or FAILED.

Of course he also wants to implement the malicious path which is supposed to tell the user about the cause of an issue. Now here's the problem (not even sure whether this only occurs in the asynch case):
Looks like SAP environment does not retrieve the body if the HTTP 500 is raised. Anyone here who can help? At least return some feedback? I have no sufficient knowledge about SAP to deal with it's strength and weaknesses

Best regards,
Bernd

Hi Bernd,

I am wondering if the proxy call in ABAP does not return any error message in the occurring SAP exceptions. But I assume your client has already checked this.

If not, maybe it could be a workaround not to call the xServer by the proxy class, but with a regular HTTP call. Function module HTTP_GET and/or class cl_http_client seem to be able to return a http body. Unfortunately, I can not test myself in my environment. Payload for the request in the fetchXXX methods is not too big and could therefore built up easily even in an ABAP environment.

Regards,
Frederik

Hi Bernd,

I suggest to request xServer by Service Consumer (SAP Enterprise Services) instead of using CL_HTTP_CLIENT. Service Consumer uses SAP SRT (SAP SoapRunTime).

With CL_HTTP_CLIENT you have to handle response, request and headers by yourself. With Service Consumer you can use transaction SRT_LOG to have a lookup to status codes not equal HTTP-200. It bases on table SRT_UTIL_ERRLOG. From that table you may read entries selected by e.g. TIMESTAMP, USER, IF-NAME or TRANSACTION-ID. With method GET_FORMATTED_DATA in CL_SOAP_XML_PARSER you can transform content of field ERROR_CONTENT to SAP STANDARD TABLE (SRT_XML_FDATA_TAB).
But how to get/create the Service Consumer? You may take the xServer-WSDL and create Enterprise Service with SAP Wizzard, but this is not simple, according to my experience. But there is the possibility to get the Service Consumers from PTV (have a look to the use cases of your xServer).

Hint: all operations START[], FETCH[], WATCH, STOP and DELETE will be send synchronous. Only the started operation is asynchronous. By this TX SRT_LOG marks the request as SYNCHRON!
