When I need to configure R/3 Destination in NWDS Studio to be able to call backend connection using RFC it doesn’t give any response when I press the “Add” button. Some site says that it because I use Windows Vista or Windows 7. Currently, I use Windows 7 as my operating system.
For your information, I used SAP NetWeaver Developr Studio SAP Netweaver 7.3 SP00 PAT0000.


Then, what I need to configure is by added some line script in file SapNetweaverDeveloperStudio.ini .

Here some line script I need to add:
-Xmx512m
-Xms128m
-XX:PermSize=32m
-XX:MaxPermSize=128m
-Dos.name=’Windows XP’



Thanks for sharing this info . i have been facing the same issue
