In-Store MIM based in Web dynpro ABAP Technology

Hello,

I need some information about "In-Store Merchandise and Inventory Management (In-Store MIM)" technical system landscape for new Retail solution.

I read in "Master Guide for Retail Business Suite 7i2913" that we need one Retail Server and one ITS 6.4 Server, but then, in software mandatory components appear two mandatory components:

- Netweaver (usage type BI)

  and

- BP IS-R-SRS 1.40

Does we need an Enterprise Portal system and a BI system aditionally to Retail System and ITS server?

Is necesary a new server for ITS or it's posible to use embedded ITS from SICF.

Thanks.
