hannes1,
    It is my understanding that the only reliable interface to SAP involves ABAP code, due to the extensive use of queing and intermediate state engines.  Direct access to the underlying database should only be done in the case of BW (business intelligence) tables.  Those tables may be accessed just like any other in the database technology (usually Oracle, lately SQL Server in smaller enterprises).

    You may be able to use a combination of Oracle and ADO to accomplish your goals.  Here is a link to Oracle's Warehouse Builder which includes SAP gateway:

(Note this site requires registration, but it is free)


And Amazon had some interesting results when I searched Books for "SAP".

Good luck!

SAP do not support .net because it is not cross-platform.

If you want to write your own SAP client-side functionality, there is a java class that comes with SAP that provides access to something called RFC (remote function calls).  RFC allows an external application to make calls to internal SAP functionality.  You write the functionality you need in SAP with ABAP, and expose it to RFCs.  Then the java class will expose your functionality to your client-side application.  You write your client-side application to call methods in the java class.

I think you can also do it in C++, but SAP really aren't interested in making things easy for Microsoft to take away chunks of their application-space - they will always make it easier to write cross-platform code using java/xml etc.

Just a further note:  SAP publically stated their intent not to support .net due to lack of cross-platform applicability (Financial Times, London, sometime late 2001).  

SAP's reasoning was something along the lines that if they were going to support .net, they would have to develop, maintain and support two separate versions of their application - one for .net, and one for all other platforms that all their customers use.  They had previously approached Microsoft to discuss a way of using .net that conformed with the standards everyone else uses, but MS turned them down.
