SAP .NET Connector Connection problems

129 Views

Hi all,

is anybody able help me solve this problem:

<b>Environment:</b>

SAP Preview 6.20 BSP on seperate WIN2K-server;access TCP/IP

Develop machine W2K SP4

GUI File Version 6402.2.3.978 Build 687100

Microsoft Visual Studio 2003 Version 7.1.3088

SAP .NET Connector 2.0.

librfc32 version 6403.3.69 in system folder

A c# program accessing the sap bapi Rfc_Get_System_Info raises an exception of this kind:

<i>Connect to message server failed

Connect_PM MSHOST=mdm1, R3NAME=BSP, GROUP=PUBLIC

LOCATION CPIC (TCP/IP) on local host

ERROR internal error

TIME Sat Jan 07 11:49:21 2006

RELEASE 640

COMPONENT MS (message handling interface, multithreaded)

VERSION 4

RC -101

COUNTER 6</i>

the exception is raised by the program instruction

<b>results = this.SAPInvoke("Rfc_Get_System_Info",new object[] );</b>

The proxy is created by

<b>m_connectString = this.mdm1_destination.ConnectionString;

infoProxy = new SAPInfoProxy(m_connectString);</b>

The destination object is customized by saplogon.ini OR manually. Result is always the same.

<b>Maybe these hints gives you an idea</b>:

When invoking SAPInvoke my firewall requests me to access the internet but i am working in a local network and all addresses are IPs.

The program is working fine on a WIN XP Client host ( V 5.1 Build 2600 xpsp2 )
