We are trying to install Fiori on EHP6 for SAP ERP 6.0 and SAP NW 7.0. We found out that in order to install the Fiori and Gateway components like GW_CORE, IW_BEP etc. we also need to upgrade some of our already existing components like BI_CONT 747, EA-APPL 606 FI-CA606 etc.
Our concern and my question to you is:
Will this upgrade, of the already existing components with ACPs, have any side effects to our system and how the established processes work? Can these attribute change packages affect somehow the system if they do a change on already existing attributes of those components that are already in place and working?
Please help me understand what it really means to install an ACP that upgrades the existing components.
