I have installed SAP BO EDGE 4.0 Platform on a 64 Bit Windows Server. Some weeks ago I have updated it to SP 2 Patch 13. There are installed BI Clienttools SP 2 also.
I would like to update to SP4 newest patch. Unfortunately I get a warning message (in German so a free translation):
Setup has detected if installation is going to progress it could be the case you could possibly uninstall patches already installed on the system. Please look at http://www.service.sap.com/bosap-maintenance-schedule to verify you are going to install a compatible patch.
Do I read this document right that I need to install SP 2 Patch 20 instead of the latest Patch 21 of SP 2 to upgrade to SP 4 ?
