Run Transactions from SAP EP iView

Hello Gurus,

I have configued an SAP transaction iView in Portal for running some transcation say "ptfc". I have configured user mapping for single sign on between EP and ECC.

Do I need to have SAP GUI installation for this to work?

My idea is to eliminate the SAP GUI installation from the client machine.

For this, should I use:

A. SAP GUI for JAVA

B. SAP GUI for HTML

C. SAP GUI for Windows

Please help.

Thanks,

Karan
