Hi GS
The MATDOC will be a line item transparent table. There is no concept of aggregates in S/4 HANA. In traditional ECC, when you wrote a report on MKPF and MSEG, it will fetch the data based on some variables into an internal structure. The system would read the complete tables based on those parameters and than hold the relevant data into structure and than display the same into a report.
However, in S/4, since HANA is a columunar database, the system directly goes to the specific value and shows in a report or query. Morever, this is just one table and not two as earlier. So the processing is much faster.
I have tried to answer in simple way on how you can expect data to flow in S/4 HANA and why it is much better than traditional ERP.
