WD Application connecting R/3 without message server?

[Former Member]

Hi Experts,

one information required. Is it mandatory to have a message server usage when I try to connect R3 BAPI from Web Dynpro? In the system I am trying to connect I only have a dedicated application server - no message server or CI is there. So how do I create the SLD system object - and what message server port should I mention there? My system no is 32 - so should I use 3632 as the port number is SLD configuration for the system object? How does it occur when we dont have a message server? Please clear this concept out to me..

Thanks a lot...

Shubhadip,

If you are connecting via JCO or SAP Enterprise Connector you may use either message or application server. If you are connecting via Adaptive RFC Model then <b>message server is mandatory for <i>metadata</i> connection</b>. Also it's highly recommended to use message server for <i>data</i> connection to utilize load-balancing.

Hi Shubhadip,

Message Server Port number always: 3600 + system number or instance number R/3.

Central Application Server = Sapxx + system number.

Login to R/3 system -> system tab in menu followed by click on status field there you will find all R/3 details..
