Do We Need to Install GUI for just executing BI 7 reports
Do we need to install SAP GUI if we just have to execute BI 7 reports. If it is not possible is it the same with both Java and ABAP stacks or is it only with the Java stack that this is possible
Review Note 1013140 - BI Frontend / BW Add-on - General Information & Limitations and Note 1013139 - Pre-requisite for BI 7.x Frontend
From Note 1013140 :
BI Standalone frontend 7.x
The new frontend tools are made standalone. It means that you can install the Business Explorer without using the SAP GUI. In the earlier versions, Busines Explorer( BEx )tools were installed as an add-on to the SAP GUI.
As far as the need for the java stack, it is not needed if you are only going to run BEx (Excel) Analyzer. The java stack is only needed for the new Report Designer, any web designer queries, or anything you are publishing via Information Broadcasting.
