SAP Fiori - Architecture

The key components in high-level landscape of SAP Fiori architecture are given below.

SAP Fioriアーキテクチャのハイレベルランドスケープの主要コンポーネントは以下のとおりです。

SAP Web Dispatcher (Reverse Proxy)

SAP Web dispatcher is the first point of contact in SAP Fiori architecture for end users. This handles all web browser requests from end users via mobile devices or laptops.

SAP Webディスパッチャーは、エンドユーザーにとってのSAP Fioriアーキテクチャーの最初の窓口です。 これは、モバイルデバイスまたはラップトップを介したエンドユーザからのすべてのWebブラウザ要求を処理します。

It is an entry point for all HTTP/HTTPS requests and defines if a system has to accept or reject the requests and the server where request should go. It can reject or accept connection to SAP Fiori system.

これは、すべてのHTTP / HTTPS要求の入り口であり、システムが要求を受け入れるか拒否するか、および要求をどこに送るべきかを定義します。 SAP Fioriシステムへの接続を拒否または受け入れることができます。

Transactional apps can run on any database but Fact sheets and Analytical apps requires SAP HANA database to run.

SAP ABAP Front-End Server

SAP ABAP front-end server contains all the UI components of Fiori system and NetWeaver gateway. These UI components consist of central UI add on, SAP UI5 control library and SAP Fiori Launchpad. It also contains product specific UI. Add-ons contain UI development for respective business suite such as ERP, SCM, SD, MM, etc.

SAP NetWeaver Gateway is used to setup a connection between SAP business suite and target clients, platforms and framework. It offers development and generation tools to create OData services to different client development tools.

SAP ABAP Back-End Server

SAP ABAP Back-End Server is used to contain the business logic and the back-end data. Search model for fact sheets and SAP business suite is contained in ABAP back-end server.

SAP HANA database and HANA XS Engine

HANA XS engine is used to run all analytical apps in SAP Fiori. It contains Fiori app content and virtual data-model reuse content, which is provided through SAP HANA Live.

HANA XS Engine consists of two components −

• HANA Live App content for Business suite.
• Smart Business component with KPI Modeler.

HANA Live content contains VDM reuse content, which can be used for extensibility purpose.

Notes −

• Transactional apps in SAP Fiori does not necessarily require SAP HANA database to run and can run on any database.
• Fact Sheets, Analytical apps and Smart Business run only on SAP HANA database with no exceptions allowed
• HANA is required for search model function of Fact Sheets to work.
• The data requested in Fact Sheets via search models is directly pulled from HANA database.

SAP Fiori Architecture: App Types

SAP Fiori apps are divided into three categories. They are distinguished on the basis of their function and infrastructure requirement.

As mentioned earlier, Transactional apps in SAP Fiori does not necessarily require SAP HANA database to run and can run on any database. Fact Sheets, Analytical apps and Smart Business run only on SAP HANA database with no exceptions.

The picture given below shows SAP Fiori Architecture for SAP Fiori different apps types.

Fact Sheets require Search models to perform search capability in Fiori Apps. Fact sheets are used to drill the key information and contextual information in business operations. In SAP Fiori tiles, you can drill down to further details. It also allows you to navigate from one fact sheets to all its related fact sheets.

Analytical apps and Smart Business apps data come from HANA database through HANA XS Engine.

HANA Live content contains Virtual Data Model reuse content, which can be used for extensibility purpose.

The user places request via Web browser using HTTPS. Trusted RFC is used to communicate between ABAP Front-End and Back-End server.
