In our company we plan to set up the SAP Enterprise Portal (NetWeaver 7.0). The first application we want to provide inside the portal is the SAP GUI that connects to our SAP ERP 2005 system via single sign on. Therefor two different approaches exist:
1: Using the standard SAP GUI inside a portal iView. In this case every client pc needs the SAP GUI installed.
2: Using the HTML SAP GUI. In this case we have to set up the integrated ITS in our SAP ERP system.
Now I have some questions about the second approach. Is the functionality of the HTML GUI equal to the functionality of the standard GUI? If not, what are the restrictions? How high is the additional load on the network and SAP ERP system caused by the HTML GUI? Would you recommend this approach for a system with more than thousand SAP users?
