Advantages of new solutions
The advantages of S/4HANA and BW/4HANA products that are primarily emphasized by SAP are the simplification of the system and elimination of the baggage of expanding and complex data structures created over the last 30 years. This aspect itself has a positive effect on the properties of new systems. It significantly increases their performance (e.g. when saving a financial document, data are recorded in one central finance table instead of being stored in more than a dozen separate tables, often redundantly).
In addition, the simplification of structures facilitates reporting. There is no need any more to combine data from multiple tables, taking into account exceptions from the combination rules in programs. A simple SQL query can quickly extract the required data from the system at a high level of detail, efficiently and online.

Another advantage of the new architecture is the reversal of the trend of separation into individual SAP systems of different products (e.g. a separate ERP system, a separate demand planning system APO a separate warehouse management system EWM). In the new architecture, many elements can be installed additionally in the ERP S/4HANA system as add-ons. Many of them are also included directly in the standard, which greatly simplifies administration, increases the system reliability and reduces the costs of hardware and configuration of interfaces.
In the case of S/4HANA, the new system includes also new features that were not available in previous versions. An example is a completely new module for cash management, SAP BPC planning integrated with the ERP system, new transactions for reporting line items, taking into account the aggregation of data when a report is being executed.
The SAP S/4HANA has received a completely new user interface in the form of SAP Fiori (HTML5). In the case of S/4HANA, 1610 release (the latest one at the time of writing this article) there are more than 7,000 transactional and analytical applications. In most cases, the user will be able to forget the old SAP GUI interface and switch to completely new transactions, not requiring the installation of special client software (using a browser).
