NW BI and EP usage - landscape

[Former Member]

Hello

We have multiple R/3 , BW and other SAP soluitions.

We also have EP (NW04S) connected (JCO to R/3 470 and BW 3.5)

We plan to upgrade to BW7 and upgrade our SEM to SEM602. the BW needs

NW with BI usage.

I hate the idea of having NW WAS for every solution. can I use the EP WAS and expand it to support BI usage from multiple BW systems? will it be wise?

THANKS

Hi Erez,

I think there might be a little confusion in the terminology here. When you upgrade BI to the 7.0 release, it becomes SAP NetWeaver 7.0. Most BW systems are only based on ABAP prior to the upgrade. After the upgrade the new BI frontend requires java based software (the 'BI Java' usage type).

Every BI system typically requires its own BI Java as the BI JAVA most be in synch with the connect AS ABAP based BI backend. It is a single system with ABAP and JAVA based functionality so sharing a BI Java will not be a good option from a support viewpoint.

Every SAP NetWeaver ABAP or JAVA based system runs on the SAP NetWeaver application server so it will be present in nearly all systems.

Additional information is available in the SAP NetWeaver master guides. I would suggest you check out the section on using a federated portal configuration for all your systems.

I hope this helps,

Mike.

Hi Michael

My point was to reduce the number of WAS engines need to support the solutions.

If now for running 6 production landscape (R3 and BW, EP) I will now have to run dual stack WAS for every one of them.... multiple that with Dev and QA systems....

Thanks

Hi Erez,

You do not need to have a ABAP Stack with your EP deployment. BI requires one as of the 7.0 release. SAP R/3 typically does not need Java until the SAP ERP 2004+ releases and then the need is based on the scenarios you wish to deploy - so I would wait to install/deploy it until you really need it.

I hope this helps,

Mike.
