I need some help to develop a SAP interface that can make communicate between SAP application and our application. I am pretty new to SAP. I have installed PDK and Sneak Preview SAP NetWeaver 2004. I dont have any other SAP product on my system.
Do I require any SAP product or SAP membership to perform these tasks or is it part of SAP NetWeaver 2004? Where from I can start if I m not SAP customer or partner?
