JCO_ERROR_COMMUNICATION: Group PUBLIC not found

Hello,

While setting up the ABAP-read help values job, we came across this error message preventing of from proceeding:

sap.conn.jco.JCoException:
(102) JCO_ERROR_COMMUNICATION:
Connect to message server host failed

Connection parameters:
TYPE=B DEST=R3D100
MSHOST=XXXXXX22211
GROUP=PUBLIC
R3NAME=R3D
PCS=1

LOCATION   
CPIC (TCP/IP) on local host XXXXXX22211 with Unicode

ERROR       Group PUBLIC not found

As I wasn't able to find any discussion on this error on the forum (this might have changed now) I broadened my search to google and found the following link:

http://www.stechno.net/sap-notes.html?view=sapnote&id=1155884

Further done the page I found the answer I was looking for in:

JCoException: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed

Connection parameters: TYPE= ... GROUP=<group> ...

LOCATION    CPIC (TCP/IP) on local host with Unicode

ERROR       Group <group> not found ... 

Use transaction SMLG in the specified communication system to determine the logon groups that exist there or to create the required logon group there

After connecting to my ABAP system I managed the logon group via transaction SMLG and the error was solved.

Just wanted to share with others who might experience a similiar error.

Cheers, Paul

    Always good to share solutions to errors. What was unexpected was the in DEV systems we don't always create logon groups, but this is an easy fix now.

    Thanks for updating with the solution. Yes, that's right. You would have to maintain logon groups using SMLG Tcode in the ABAP system.

    Cheers,
