Hi Johannes,
Please note that for publishing reports with Web Application Designer 7.x ABAP(7.0x) Stack needs to be configured with Java(7.0x) Stack as per the following SAP Note:
917950 - SAP Netweaver 2004s: Setting Up BEx Web
Also, please do not use report RSPOR_SETUP for configuration check for SAP NetWeaver 2004s. This report has been replaced by the Support Desk Tool. Please have a look at the following
SAP Note regarding Support Desk Tool:
937697 - Usage of SAP Netweaver BI Diagnostics & Support Desk Tool
The report RSPOR_SETUP is obsolete in BI 7.x release and Support Desk Tool should be used in 7.x Release
And, please note the following;
"With SAP NetWeaver 7.1, the Visual Administrator (VA) is replaced by the SAP NetWeaver Administrator, that is, all relevant functions of the Visual Administrator are available in SAP NetWeaver Administrator. The Visual Administrator is no longer delivered as of SAP NetWeaver 7.1"
Thanks & Regards,
Sapna
