AS2 URL: working with multiple trading partner using a proxy

[#1]

Hi All,

We are implementing SAP B2B add-on in our landscape.

My question is similar to what is mentioned @

We are planning to configure a proxy server to redirect the request from multiple trading partner.

My questions are :

Do we need to maintain separate AS2 URL on the proxy server to identify the sender and redirect the requests to PI?

Can't we have the same "expected URL-path" in AS2 sender channels(for each partner)  but maintain separate AS2 name under "Expected Sender AS2 Name" attribute?

     -> This way all partners will be provided with the same URL(proxy server)

     -> proxy server will forward all the requests to same URL(PI AS2 URL)

Do we need to maintain the Proxy server details in order to send the MDN back to partner?

Appreciate your help.

Thank you.

Hi Hareesh,

As far as I know, you can try it with the same URL path in the AS2 sender channel. The target for each partner is the same, your SAP PI system. Of course, the identification differs between different partners.

Concerning the MDN you're going to send back: I'm not sure, but I do not think proxy server maintenance is necessary because the connection between your partner's system and your SAP PI system is already there.

Try it out and play with it to see if that concept works (for you).

Please do share your experiences/problems within this thread.

Kind regards,

Dimitri

Thanks for the quick reply Dimitri.

>>> The target for each partner is the same, your SAP PI system. Of course, the identification differs between different partners.

When we maintain the same URL, how can we identify the partners? Partner's are not directly communicating with PI right?

I assume we create separate sender channel for each partner.  In all our channel's we maintain the same value for the attribute "expected URL path " letz say "mycompanyas2".

Now Partners will be sending the AS2 message to Proxy URL : http://mycompany:port/AS2

proxy will redirect the request to AS2 URL : http//host:port/AS2/mycompanyas2.

Now my question is how does my sender channel react as all of them would be looking for the message at that URL.

Configuring a distinct "expected sender AS2 name" would solve the issue?

Appreciate your time and help.

Actual implementation may still take some more time but as a pre-work we are trying to evaluate these factors.

Hi Hareesh,

Have a look at the SAP help about the configuration for the AS2 sender adapter.

You can use the Expected URL Path and Expected Sender‘s AS2 Name to differentiate.

On step further in the configuration is the usage of the EDIseparator adapter. Please have a look at this to try to make your concept complete

Kind regards,
