Questions about ABAP Function making outbound RFC-JCO call

[Former Member]

Hi,

I have 2 questions as below:

1. Is it possible for Java application to return a ABAP system exceptions(0,1,2 and so on) to the called ABAP function (RFC JCO Connection), when there is a java application exception occured? Assume this Java application is deployed in NWWAS.

2. Is it possible for ABAP function to make a RFC-JCO call to a remote Java application (<b>NOT</b> deployed in NW WAS, perhaps some other J2EE/web server)? If yes, please advise on how to do that.

Hi,

1.) Sorry I've never seen this. I believe there is something similar with adaptive RFC's but it is recommended that you do not throw exceptions in RFC's / BAPI's.

2.) Yes it is possible for an ABAP function to make RFC calls but you will have to set up RFC destinations in sm59.

Here is a blog for sm59 https connection settings:

Further the BC Connector or XI (PI) can help serve as an extraction layer for system to system communication. One quick and dirty way to do this is to call a web service with the HTTP_POST function in ABAP and use ABAP xml classes to parse the response. This is not a recommended way but it gets around any kind of configuration.
