HTTP Destination in Proxies

[Former Member]

Hi all,

In ABAP Server Proxies (inbound) scenario, I have found that HTTP (type H) connection has been created, instead of R/3 Connection (type 3) to SAP from XI.

Please let me know the advantages of using such connection type H instead of connection type 3 in SM59 in case of Inbound ABAP proxies.

Thanks in advance.

Regards

Krishna.

hi krishna,

this link may help you to understand the RFC types:

Typically u use R/3 connection for traditional R/3 to R/3 communication e.g. IDoc communication.

In ABAP server proxies the XI Proxy runtime makes HTTP call to target ECC system using type H connection.

One benefit i saw is we could remotly debug our proxy code with this.

Hi,

What I understand from your replies is, in case of ABAP Proxies the connection type should be HTTP for R/3 system.

Does it mean we can not work with type 3 connection in case of ABAP proxies?

In such case, as XI sends the data to R/3 in XML format with HTTP connection, Can R/3 able to handle that message with proxies? If yes, how?

Regards

Krishna.

hi krishna,

XI uses HTTP protocol to send data out ( say XML). To send to ABAP proxies we use adapters in the XI which will convert the message as needed by the R/3.

XI and RFC uses different adapters(protocols).

To push/extract the data into/from R/3 system we use Proxies (Inbound/outbound). So creating the Type 3 RFC destination will not full fill the requirement as said above. To commuincate with proxy there should be only type H conncetion to communicate with XI.

Type 3 : ABAP Connection to any SAP system .

We use this RFC destination to push IDcos and making RFC calls to SAP systems.

Type H : http connection: to connect to the target system using http transport protocol. example to send xml message to target sap web server.
