Hi Vishnu,

• Are you using any proxy between ECC and PI, Check the proxy server is up and running?
• There will HTML error also you can find it in sxi_monitor, check the html error for more detail about the error.

Do you use Microsoft ISA server in your landscape? If so, error can be caused by proxy communication failure.

Contact your ISA server admins to set up proper communication between ECC and ISA Server.

Hi Kolmakov,

I think there is a ISA Server.

I will check with ISA team.

Hello Praveen,

Are you triggering Proxy messages?

I Guess the server is not up and running.

[vishnu_pallamreddy]

Hi Raghu,

We are triggering Proxy Messages.

I will check on Proxy Server.

Hello Vishnu,

Please check if the proxy connectivity settings are in place b/w ECC and PI.

Thanks

Venkat.

Hi Venkat,

We are getting message failures for only one interface and we have successful messages for remaining interfaces.

Vishnu check the below discussions

Hi Vishnu,

The error seems to be in the ISA server, they can have a firewall or anti-virus blocking your connection: ISA 2006 502 error

Regards.

[vishnu_pallamreddy]

Hi Inaki,

So could you please confirm me, the issue refers that ISA Server is there in between SAP ECC and SAP PI right?

[former_member190293]

Microsoft Security and Acceleration server is a proxy server and firewall software. And it can block the network traffic if firewall client or proxy settings are set up incorrectly.

[former_member190293]

It's rather possible, that PI server stands behind ISA Server which controls inbound and outbound traffic. In that case you can receive error messages from ISA Server.

Hi Vishnu,

If ERP and PI both are internal systems and with in the same network actually you don't need proxy server between ERP and PI. You can configure don't use proxy server for PI system.

Praveen.

Hi Vishnu,

Generic connections are enough in case of Classical Scenario. In case of AAE, you need to have a Sender/Receiver configuration on ECC for each interface. If you are on Classical Scenario then please ignore my replies.

Thanks

Venkat.

[vishnu_pallamreddy]

Hi Praveen,

How can we configure Do not use proxy option.

Where can we found that option? in RFC destinations?

[former_member182412]

Hi Vishnu,

You can see below screen shots.

Regards,

Praveen.

[vishnu_pallamreddy]

Thanks Praveen,

I will check.

We need to check in SAP ECC system right?

and we are getting failures for only one interface and remaining interfaces are running successfully.

[former_member186851]

Hello Vishnu,

Then I believe this setting is not required.

Any specific pattern or something different in the failing interface?
