Hello Paul,
When SAP removed the above table including KNC1, it changed them to view.
This was to ensure that all client custom development which are reading from these tables would still work.
So if I compare you KNC1 in Sfin vs non Sfin, you can see the difference in definition
This is in SAP ECC non Sfin..see that KNC1 is a transparent table with data being stored in Db level.
Now check KNC1 in an Sfin system
Now you see KNC1 is a view , so it does not own its data at the HANA db Level.
That is the advantage of Sfin, where all the aggregate tables are removed and changed as view.
This reduce the data footprint and provide quicker access ( that is due to other factors too )
Hope this answers your question and we would love to see your final video and how it come out
Regards & have a good day
