You might think that we already have a blog on SDN about configuring ABAP proxy communication with PI 7.3 - Proxy Configuration for PI 7.3 Java only but it turns out the config does not have to be that difficult as shown in the other blog. Let me show you how.
How to connect any ABAP based application system to AEX ?
1. First of all we need to start with creating a new RFC destination type G - SAP_PROXY_ESR:
a) please put the AEX server host name and port
b) path is /rep
c) user in the logon tab needs to be assigned to role SAP_XI_REP_SERV_USER
Now the important things:
1. If we have the SAP_PROXY_ESR destination we don't need to create LCRSAPRFC as it's obsolete if you use SAP_PROXY_ESR.
2. SAPSLDAPI is also not necessary for proxy connectivity in terms of connecting it to PI server and you don't need to create any Jco RFC provider destination on AEX - in most cases you will connect to a central SLD (probably on SOLMAN) anyway. Just make sure the SLDCHECK is working on your SAP backend.
How to create an HTTP destination from ABAP based application system to AEX ?
The second step is to create an HTTP destination to AEX:
a) please put the AEX server host name and port
b) path is /XISOAPAdapter/MessageServlet?ximessage=true
Next you just need to add this destination in SXMB_ADM --> Integration server config --> Global configuration - link
Was that much easier this time ?
