Hello,
my name is David and actually i compose my bachelor thesis.
In the first step of my project I have generated the relevant SAP-Queries via Infosets (sq03 --> sq02 --> sq01) in SAP. Now i try to get a connection between Crystal/Xcelsius and my ERP-System (reports), but i dont know how...the problem is i need a direct connection from the BO-System(Crystal/Xcelsius) to SAP. 
The first idea was to use the web service connection in crystal/xcelius, but i dont know how to get an access to the reports in SAP (which transaction did i need, what have i to do?) A http connection via transaction "sicf" is available.
If it is not possible to get a direct connection to my generated reports, whats about to generate a function module (Web Service in ECC) to get access to a table who already exists in SAP ?
I hope someone can give me assistance and tips to get my project done 
Thank you so much for your help!
kind regards!
David
