CONCATENATE 'http://evatr.bff-online.de/evatrRPC?UstId_1=' p_ustid '&UstId_2=' pu_ustid

   '&Druck=nein' INTO i_url.





CALL METHOD cl_http_client=>create_by_url

   client  = i_client



call method i_client->send

Hi ,

Can you please help me solve this error?

When i am using "CALL FUNCTION 'HTTP_GET'". I am getting the result in some XML format.

But when i use create, send and receive as in original post, I am getting communication error in the receive method.

Thanks in advance ,

regards,

NarsiReddy Cheruku.

Hi,

A communication issue might mean that the SAP system may not be able to connect to host evatr.bff-online.de .

To test this get your infrastructure guys to "telnet" from the SAP instance operating system to that host with port 80.

It is not likely your SAP environment will be allowed (due to firewall rules) to directly access the internet. This is pretty normal in most companies.

You may need to go via a proxy server (see importing params PROXY_HOST and PROXY_SERVICE of method CREATE_BY_URL), if your company has one available to go out to the internet from your network. Your infrasructure team should be able to help confirm this and tell you the details.

Hope that helps.

Cheers,

Katan
