Overview of SAP S/4 HANA - comparison of general DB based vs. HANA DB based vs. S/4 HANA

Structural change

Simplification of data model/volume

Comparison of SAP S/4 HANA building strategy(example)

When SAP S/4 HANA is built, you can convert existing system or build a new system. However, considerations need to be given to various aspects.

  Conversion method New installation method
features All the existing data are maintained (history, reference information, config, etc.) Downtime is minimized during works in the event of new configuration.
changes in SAP business procedures It is not easy to change the master system massively and change the config for the process innovation, although the existing config etc., are maintained and there are not many changes in works. As it is new configuration, full-scale improvement is needed for master information, config, etc.
  • Constraints such as patch version, Unicode, etc.
  • Downtime occurrence during the use of DMO
  • As the procedure for conversion is very complicated and requires several pre-validation procedures, much effort is taken for works such as replication of existing system, etc.
There is no history data. Therefore, measures may be needed for migration or inquiry as necessary.
Preconditions Conditions such as patch version required by SUM + DMO
