Hi,

As per this blog, check if you have not missed anything in R/3 system.

Also, i wanted to know eher in r/3 or xi where do we provide address of the target system.

When u clicked on test connection in SPROXY , the system gives the following error :

503 Service Unavailable: Failed to forward the request to the web server at xiprd:50100. This may be due to a firewall configuration error or a DNS failure.

Gurus plz help.

Snehal,

Error: The error message 503 Service unavailable Application stopped! is displayed.

Description: The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.

Possible Tips: Because of J2EE application com.sap.aii.af.ms.app not active

• Try to (re)start the application using the Visual Administrator Choose Server --> Services --> Deploy --> View on Application or restart the J2EE engine

• The problem is that not all J2EE services can be started by the J2EE. i.e Start the Visual Administrator and select Server->Services->Deploy in the tree on the left. On the right-hand side, choose the Runtime tab page. You see a tree in the right window with all applications if you select the APPLICATION radio button. Check if they are running, otherwise choose Start. Usually the J2EE engine starts all services automatically.

• Refer SAP Note 803145,807000,791655

Hi Snehal,

you need to create an HTTP connection in the Application System(r/3 system).

In SM59, create a type H destination with the Target Host Name (NW server) and the HTTP port of the Integration Server. To find out the number of the HTTP port (service number), see the ICM Monitor of the relevant Integration Server (call transaction SMICM and then Go to → Services).

Under Technical Settings tab, enter "/sap/xi/engine/?type=entry" as the Path Prefix (path in the HTTP service tree of the SAP Web AS).

Under Logon & Security tab, select "SAP Standard" as authentication method. The logon user must exist in your Integration Server client as an Application Service User (Role SAP_XI_APPL_SERV_USER ).

When you try to save this destination, the system will prompt a warning message indicating "Query String not allowed". Simply press enter to ignore this warning, and save the destination again.
