There is a requirement to implement SAPUI5 in our landscape. Currently our ECC is on version ERP 6.0 EHP6. The plan is to install a new netweaver gateway system and use that to connect ECC & SAPUI5 client tools. I've few queries as part of that,
1) What are the addons that need to be installed in new Netweaver gateway system?
2) What are the addons that need to be installed in the ECC system?
3) Whether installing the addons in ECC system require any downtime?
4) Whether installing the addons in ECC impact any other components like SAP_BASIS, SAP_APPL etc?
5) Can the new netweaver system be installed with 7.4 version whereas our current ECC SAP_BASIS version is 731?
