Embedding SAP R/3 Gui into SAP EP

Hi all,

Would like to know if there is general guide/iview package/ or if you have suggestions on how to embed the SAP Gui into Enterprise Portal iview content.

Eg.

1. How to configure to launch the SAP R/3 Gui within SAP EP browser as iview(Do we need to have ITS/SAP Gui for HTML Installed or SAP GUI for windodws can launch within browser)

2. How to configure to launch specific R/3 transaction within SAP EP Browser as iview

3. How to choose whether to launch in existing window or new window(or whether impossible)

Thanks,

Alex
