.net connector 2.0 connectivity to SAP 3.1H

Hi, connector 2.0 keeps breaking my connectivity to SAP.

I have done a clean win 2000 install, installed SAP DCOM Connector and VS Studio .NET 2003 Enterprise Architect.

Connectivity to SAP works (using DCOM connector web interface).

Once I install SAP .NET Connector 2.0 I can't establish a connection to SAP. Using server explorer in VS.NET and DCOM 4.6D I get the following

"connection closed without message (CM_NO_DATA_RECEIVED)"


"SYSTEM_CORE_DUMPED occured. P1=5"

any help would be greatly appreciated!

    Unfortunately 3.x is not really supported by NCo (SAP .NET Connector). It seems that even request for the list of functions or business ojbect causes ABAP to crash ("Core dump").

    You can try if it works at least with functions (not BOR). Or you can try to create the proxies from a "newer" system with the same functions in it (e.g. 4.0B or 4.6C) and then use the generated proxies with your 3.x system.

    • Yes, exaclty. The important "Metadata" are name and type of paramters and for all structures the name, type, offset, length and precision of the fields. If this DDIC information is available in the newer system and equal to the old one, it should work.
