Hi All,

As expressed on my question, I would like to ask if S/4HANA actually remove the aggregations. I know that there are 2 new tables, ACDOCA and MATDOC which is a transparent table while MSEG and BSEG also a transparent table.

Does this means they doubled the database consumption because ACDOCA actually contains BSEG values and MATDOC contains MSEG values?

Thank you

S/4 HANA combines data structure of different components (F1,AA,CO-PA) into a single line item table called ACDOCA.

Those "eliminated/replace Tables" (like MSEG) seem to still be there, but they are not, at least not on DB-Level.

What we see and what looks like them, are just Proxy-Objects, CDS-Views to well "emulate" the removed Tables (only for read-operations);

They were once also called "equally named Objects", I thing.

You can read up on my experience when I found out about them here: https://blogs.sap.com/2016/02/02/eliminated-tables-in-s4-hana-on-premise-edition-1511-what-s-behind-them/
