Hi Vas,
Importance for BW Java Stack.
- BEx 3.5 Tools (Query Designer, WAD, etc.): they use the BEx Web ABAP Runtime;
- BEx 7.0 Tools: they use the BEx Web Java Runtime.
- Web Application Designer - Java required.
- Enterprise Report - Java required.
From Netweaver 7.4 master guide :
You need BI Java and the Java-based usage types for specific capabilities only, which are the following:
SAP Business Explorer
You need BI Java, EP Core – Application Portal, and Enterprise Portal for SAP Business Explorer (BEx) tools and runtime, for example, BEx Web, Information Broadcasting, and Portal Integration.
SAP Note 917950 - SAP NetWeaver 2004s: Setting Up BEx Web", chapter "Architecture", the note say that only Bex Web requires Java stack!
