Hello Experts,
I need your inputs on system architecture while we are undergoing upgrade from BW 3.5 to BW 7.31.
Current BW 3.5 system is used for SRM reporting. WAD 3.5 is used to publish BEx reports to the reporting roles in BW, BW roles are then distributed SRM roles. Ultimately, reports are accessed through SRM web application. We are NOT using portal and do NOT have Java stack.
My questions are -
- While we are upgrading to BW 7.31 (technical upgrade), do we need to have a Java stack in addition to ABAP stack for WAD to remain accessible through SRM Web Application (it's not a portal application)?
- What will be the java stack requirement in both the cases where we decide to migrate WAD 3.5 to 7 and to let WAD templates remain in 3.5 as it is?
- What functinality of 7.3 will we miss out if we don't have the Java stack?
- What is the best practice in case Java is required - dual stack or seperate instance ?
I will appreciate you can share the some doc link along with your suggestion for me to have clarity on post upgrade landscape.
Thanks & Regards.
