Ans. national Apps configuration steps:
Configuring SAP Web Dispatcher specifies routing rules to define which URL is forwarded to which system is done for both Transactional Apps and Factsheets.
Only needs to be configured for Factsheets. If we just have to configure Transactional Apps we can skip step 2.
The Third Step is configuring the front-end server and this is done for both Transactional Apps and Factsheets. At a high level we need to configure:
The fourth step is configuring the back-end server and this is done for both Transactional Apps and Factsheets.
Viewing from a high level – Roles, Users, and Authorizations
Note: Transactional Apps can run on any DB whereas the Factsheets must run on SAP Hana.
Ans. In NetWeaver Gateway Central Hub deployment: UI layer and SAP NetWeaver gateway is contained in the ABAP Front-end server. The ABAP back end server contains business logic and back end data. Separating business logic and back end data from the UI layer has below advantages:
Ans. By implementing SAP Single Sign-On, your apps become automatically available after just one initial user authentication at the user's Windows desktop, with no need for further log-on procedures.
Kerberos technology is the method of choice in intranet scenarios for SSO. It simply re-uses your Windows domain authentication for single sign-on.
X.509 certificates provide a viable option for creating a secure SSO infrastructure if you're considering extending single sign-on to an extranet or cross-company scenario.

Ans. In Embedded Hub Deployment NetWeaver gateway is deployed on the same server as the Business Suite. So multiple Business Suite systems require Gateway to be configured multiple times. It is not recommended by SAP especially for customers with multiple back ends.
No additional separate NetWeaver Gateway system is required. It is usually used for sandbox purposes only.
Ans. Configurations of SAP Fiori Apps are divided into two parts: Configuration of Transaction Apps and Fact sheets, Configuration of Analytical Apps.
Before configuring anything, the complete infrastructure for SAP Fiori apps must be installed. Once that is completed there will be activities to configure on the back-end and front-end servers.
Ans. SAP Hana XS engine contains 2 components-Hana Live App Content and SMART Business components with KPI modeller. Within Hana Live App Content VDM reuse content exist.
Model: A bridge between view and data of the apps and it accepts the request from view and responds accordingly. It doesn’t depend on any of the classes.
View: It manages the display of information (GUI of the application) and it depends on the Model.
Controller: It concludes the input given by devices and communicates to the model/view to take proper action. It also depends on the model. View and Controller have 1:1 relationship. The controller entertains user requests received from View.
Ans. SAPUI5 library provides a special API “sap.ui.Device“which can be used for the device and its feature detection. This API has a flag “sap.ui.Device.touch” which returns true if the device is a touch screen otherwise false.
Ans. SAPUI5 library provides a special API “sap.ui.Device“which can be used for the device and its feature detection. This API provides flags like “chrome”, “firefox”, “Mozilla”, “edge” etc. in “sap.ui.Device.browser” API which returns boolean values.
Ans. OData is a protocol used to exchange data on the web and was originally developed by Microsoft. It is based on Atom Publishing and Atom Syndication standards, which in turn, are based on XML and HTTPS(S).
The Atom publishing format doesn’t specify how Data should be encoded within a feed therefore it fails to provide self-describing messages and fails to be fully RESTful. OData extends Atom by providing a metadata description of the message.
OData defines for:
Ans. Configure the ABAP Front-end server includes- Configure SAP NetWeaver Gateway, Configure the Central UI Add-On, Configure SAP Fiori Launchpad.
Ans. There are 5 design principles we need to keep in mind while designing SAP Fiori applications.

Ans. OData services have to be enabled in SAP Net Weaver gateway to establish a mapping between the technical OData name and the corresponding back-end service. In order to set up SAP Fiori Launchpad and Launchpad designer, we have to activate 5 specific OData Services.
/UI2/PAGE_BUILDER_CONF
/UI2/PAGE_BUILDER_PERS
/UI2/PAGE_BUILDER_CUST
/UI2/INTEROP
/UI2/TRANSPORT
Ans. The different options in SAP Fiori Launchpad are:
Configuration Layer: Contains all content as delivered to customers including translation.
Customization Layer: Customers adjust content for all users in the system. We can use the CUST layer for testing or other reasons. Content is transportable through customizing requests by customers. After customization, content is decoupled from the configuration layer and no automatic synchronization after changes to the delivered layer.
Ans. The Launchpad user must have the PFCG role SAP_UI2_USER_700 assigned. With this role, the user can run the SAP Fiori Launchpad on the Personalization level and has the authorization to execute the following OData services:
/UI2/PAGE_BUILDER_PERS
/UI2/INTEROP
/UI2/LAUNCHPAD
Ans. SAP Solution Manager is the standard platform for Application Lifecycle Management (ALM) and plays a decisive role within the ALM tools. Besides providing SAP functionality itself, SAP Solution Manager integrates the other tools to ensure a comprehensive approach.
Ans. Using UI theme designer you can create your themes to adapt the visual appearance of applications.
One single tool for theming and branding SAP’s key user interfaces.
Apply your corporate branding and look to applications built with SAP UI technologies. The UI theme designer is a browser-based tool for cross-theming scenarios.
The tool is targeted at different user groups, including developers, visual designers, and administrators.
Key Features and Benefits.
Browser-based, graphical WYSIWYG editor:
Change the values of theming parameters and immediately see how it affects the visualization of the selected preview page.
Build-in preview pages:
Select built-in preview pages to see what your custom theme will look like when it is applied to an application −Application previews (for example, Purchase Order Approval, SAP Fiori Launchpad)Control previews.
Different levels of theming:
The colour palette for reuse:

Cross-technology theming:
Create one consistent theme that applies to various SAP UI clients and technologies −SAPUI5 standard libraries (including SAP Fiori applications and SAP Fiori launchpad)Unified Rendering technologies (such as Web Dynpro ABAP and Floorplan Manager).
Ans. Transaction code SE11 is an ABAP dictionary. By using this transaction code, you can create, change, and display table entries and structures. At the initial screen, you can put any tables or structures to view, edit, or even create a new one. Transaction code SE11 is normally used as an ABAP programmer.
SAP Gateway Service Builder (transaction SEGW)) is a design-time environment, which provides developers an easy-to-use set of tools for creating services. The Code-based OData Channel consumes it and supports developers throughout the development life cycle of a service.
SE80 - Object Navigator
SE 80 is a tool to develop and navigate programs and dd-obj.
SE80 Object Navigator → means all the objects will be available there. In se80 in addition to viewing the objects related to programming and classes, there are more privileges to view such as some other repositories such as mime, object repository, object browser, and all.
Ans. IW_BEP on Business Suite
IW_FND on Gateway Layer
Ans. The configuration is stored in the component.js file of the custom application. The component of the custom application needs to inherit from the main component of the original application. To make the location of the original application or component known to SAPUI5, it may be necessary to use register Module Path. The configuration in the customizing section contains the extension metadata and describes the objects that are replaced or extended.
Ans. Fragments are pieces of a UI without their own controller. The name of each view of the fragment is important. A fragment must be named as .fragment.xml and a view .view.xml
SAPUI5 Views:
Views are nothing but the application pages. We define our user interface by creating Views. Views are formed or created by using one or more Controls in it say Page, simple form,Dialog, Label, Input, etc. Every view has its own controller.
SAPUI5 Fragments:
Fragments are the pieces of UI just like SAPUI5 Views. Whenever we need to use some similar UI parts many times in our application/views we create Fragments of those UI parts because Fragments are reusable and are lightweight compared to VIews and Controls. Fragments are stored within the application itself and can be used by that application only. Fragments are defined as View only and calling Views controller is shared with Fragment as Fragments are not having their own controllers.
Ans. For Analytical apps, you need SAP Hana as an underlying database, with no exceptions. SAP Fiori leverages.
XS engine by using virtual data models. Within the XS engine, there are 2 components: the HANA Live App content for the respective business suite and the Smart business component with the KPI modeller. Within the HANA live content, the VDM reuse content exists which can be modified.
In the below Pic, you have the ABAP front end server which contains the UI Add-Ons for respective products used, NetWeaver Gateway with OData enablement, the central UI add-on, and the KPI framework. These front end components have read access to the backend data via a trusted RFC connection.
Ans. Three routing rules need to be defined in the SAP NWG system.
Two routing rules need to be defined in the HANA studio.
Ans. The Launchpad administrator must have the PFCG role SAP_UI2_ADMIN assigned.
SAP_UI2_ADMIN is a composite role containing the following release-dependent roles:
| Release | Dependent Roles |
| SAP_UI2_ADMIN_700 | SAP NetWeaver 7.0 |
| SAP_UI2_ADMIN_702 | SAP NetWeaver 7.0 enhancement package 2 |
| SAP_UI2_ADMIN_731 | SAP NetWeaver 7.0 enhancement package 3 and SAP NetWeaver 7.3 enhancement package 1 |
Ans. You need to know the system alias of the ABAP system in which you developed and configured the Gateway Service. There are two possibilities here −
If the GW_CORE and IW_BEP components are installed on the same ABAP system, then the system alias will probably be “LOCAL”.
If they are installed on different systems, then although system aliases can be any name you like, they generally follow the naming convention of _ So the system alias for connecting to client 200 of system C11 would generally be C11_200.
Ans. We can use SAP Fiori Launchpad designer for configuring and creating groups and catalogues which can then be accessed from SAP Fiori Launchpad which is a single entry point to all apps. We can search recently launched apps via the search capability of Launchpad. Tiles that are available on the Fiori Launchpad home page are configured using Launchpad Designer Tool.
Ans. For Analytical apps, you need SAP Hana as an underlying database, with no exceptions. SAP Fiori leverages. XS engine by using virtual data models. Within the XS engine, there are 2 components: the HANA Live App content for the respective business suite and the Smart business component with the KPI modeller. Within the HANA live content, the VDM reuse content exists which can be modified.
