Unable to establish connection to R/3 system

[Former Member]

Hi Guys,

I am doing one example ( connection r/3 to legacy system ) . When I open I outbound object in Integration Repository and in <b><i>Imported objects</i></b> when right click on <i><b>IDocs</b></i> and click Import SAP Objects, it asks me for SAP logon details , but when I try to connect it shows an error

<i><b>Unable to establish connection to R/3 system 192.168.70.57 (system=07, client=800) Troubleshooting tips:

Is the target system online?

Check the connection data (note that server names and groups are case-sensitive)

Tips for administrators (see the configuration guide for more details):

Does the user have the required authorizations in the target system?

Is the target system configured correctly in "etc/services"?</b></i>

Guys can anybody tell me what mistake i am doing ?

Thanks

Hi Manish,

Did you resolve this issue? I am getting the same problem.

Please let me know how to resolve this.

The only reasons I know of why this happens:

Host name resolution (not relevant if you use IP).

Incorrect System ID.

Incorrect System number.

I have seen a firewall cause this.

Apart from that need to be there to investigate. Start with logs in J2EE, etc.
