Http Error 503 Service unavailable when calling a Webservice Provider from external application

[sebastian_hockmann2]

Hello.

i had configured the SRT Runtime according to SAP manuals.
All tests in SRT_TOOLS and SOAMANAGER seems to be ok and without errors.

When i try to call a webservice provider from an external consumer i always get http 503 error.

But there is no webservice isolation active.

I had tried SRT_TEST to run some tests. But here i get errors.

E.g. when using the simple Ping test then i get a Service Ping error saying that

there is some processing error.

For another testcase i get SOAP:1023 SRT: Processing error in ICF when sending...

What maybe the reason for these errors in SRT Framework and for the 503 error.

But the same tests running properly on the testsystem.

Thanks a lot for your ideas and input 🙂

Best regards,

Sebastian Hockmann

Hi,

Many issues cause this error. In my case it was the 'CERTIFICATE' issue. I got the same error when i was calling the web service from sales force. The reason i got this error was I did not load the correct sales force CERT in SAP under TCODE: STRUST.

Best way to find out is error is:

1. Goto tcode: SMICM

2. Menu goto->trace file>display all

3. scroll all the way to the end and find the error based on the time you ran the service call.

You should get some idea about what is going wrong. If it is the CERT issue, work with basis team to upload the certificate.

Hope this helps,
