Per SAP Note 2643245
"All RTC views are delivered as HDI views as well as HANA repository views in S/4HANA 1709 and both versions can be used"
Is Web IDE as RTC Hana Views development platform, a MUST or NICE-TO-HAVE for S/4HANA 1809? Can we perform all the RTC modeling in 1809 FPS01 using Hana Developer Studio? Or do we need to mandatorily move to Web IDE to develop Hana Views for RTC Matrix Consolidation?
