Executive Summary
• Problem:
You want to leverage a new proprietary Fiori App with your SAP system on premise
• Solution:
Create an Fiori App accessing your SAP on IBM z Systems with Eclipse
• How to:
- Learn via sample Fiori App
- Use an IDES Installation because it already contains a SAP Gateway setup
(IDES ECC 6.0 incl. EhP7 Edition 2 (2015))
- Select common scenario: SAP Business Suite ‘Purchase Order Approval’ application
- Implement sample described in two SAP Community Network blogs

Positioning SAP Fiori and IBM Solutions
• SAP Fiori Apps are SAP‘s Mobile Solutions
• Ready to run mobile apps for different SAP back-
end applications; allow for easy extensions
• SAP-centric
• Own Fiori Apps: Deep Application knowledge is
the prerequisite
• IBM MobileFirst Platform
• Custom-development of mobile solutions
for „Individual Enterprise“ transformation
• For Apps which access different on-premise
sources, both SAP and non-SAP APIs
• IBM Bluemix
• Modern and fast dev. environment; offers
„MobilFirst Services Starter“ boilerplate*
• For Apps which access both SAP and Cloud
APIs
• Public Cloud deployment
* boilerplate: contains an app and its associated runtime environment and predefined services for a particular domain.

SAP Fiori
• SAP Fiori is the new user experience (UX) for SAP software. It applies modern design
principles for a completely reimagined user experience. SAP Fiori UX represents a
personalized, responsive and simple user experience across devices and deployment
options. See SAP Fiori - SAP User Experience Community
• SAP Fiori Apps are developed by using User Interface Development Toolkit for HTML5
(SAPUI5).

SAP Fiori User Interface is build with SAPUI5
• The SAPUI5 runtime is a client-side HTML5* rendering library with a rich set of UI
controls for building as well desktop as mobile applications.
• Sample Fiori Purchase Order Approval application**, which is based on SAPUI5
technology looks on iPhone 6 like below.
* https://de.wikipedia.org/wiki/HTML5 ** http://scn.sap.com/docs/DOC-53949

SAP Fiori App Types
Only transactional Fiori Apps run currently on Any DB Option: HANA as a sidecar

SAP Fiori App Catalog
• SAP Fiori Apps reference library:
– fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer
• SAP Fiori - SAP Help Portal Page
– help.sap.com/fiori
• Some Analytical Fiori Apps are called SAP Smart Business
• Example for Transactional Fiori App: My Spend
– SAP Fiori principal Apps 1.0 for SAP ERP
– Back-End product supported by : SAP ERP 6.0 SPS 15+, etc.

SAP Fiori – requires SAP Gateway and OData
• SAP Gateway is a mandatory component to run SAP Fiori apps. SAP Fiori apps use OData services
(REST API implementation) to display and update data in the backend.
• OData service is based on a Entity Data Model (EDM) which can be created in Eclipse and imported
into SAP Gateway. During import via `SEGW` transaction ABAP classes and stub OData Create /
Read / Update / Delete (CRUD) methods are created to access the data. The ABAP code of the
methods must be developed.
See http://scn.sap.com/docs/DOC-46223
and refer to Generated ABAP Classes and Service Registration - SAP NetWeaver Gateway - SAP Library
• The ModelProviderClass (MPC) is used to define the model, e.g. method ‘Define’ creates entity,
properties, etc.
• The DataProviderClass (DPC) is used to code your CRUD methods as well as function import
methods. All the logic must be coded in redefined methods of DPC extension class.
• The UI is coded in JavaScript and XML

Architecture of Fiori Transactional Apps –
Intranet Deployment
 Details
 Apps are deployed by ABAP UI add-ons,
SAP Fiori Lauchpad to start an App
 Apps are connected via OData services
based on OData models
 OData services are shipped via ABAP
Support Packages
 SAP Gateway:
 Handles communication between client and SAP backend
applications using OData services and processes HTTPS
request for the OData services
 Makes your SAP business data and functionality accessible to
any external device

Architecture of Fiori Transactional Apps –
Internet-Facing Deployment
 SAP Fiori Client
 Mobile application runtime
 Available for iOS, Android, Windows
 Provides e.g. asset caching or device API access
 SAP Web Dispatcher (or equivalent) in DMZ
 SAP Mobile Platform (optional) for additional
management capabilities like:
 Enterprise authentication
 User/device registration
 Application lifecycle management
 Usage statistics
 Details
 Alternative deployment on SAP HANA Cloud Platform

Development environments for Fiori Apps
• Developing Fiori Apps in public cloud: SAP Web IDE
 Overview and introduction to Web IDE: scn.sap.com/docs/DOC-55884
 Apps can be deployed on ABAP Server with SAP Gateway or on SAP HANA Cloud Platform
(HCP)
• Developing Fiori Apps on premise: Eclipse
 Eclipse plugins available for download at
tools.hana.ondemand.com

Development of a Fiori ‚Purchase Order Approval‘
App with Eclipse
Information is described in three SAP Community Network sources:
 Fiori-like Purchase Order Approval with OData - Part I (Fiori-like SCN Part I)
http://scn.sap.com/docs/DOC-53949
describes the SAP backend ABAP Logic, OData Model and SAP Gateway configuration
 Create your first service with SAP Gateway 2.0 SP4 (Gateway SCN)
http://scn.sap.com/community/developer-center/mobility-platform/blog/2013/04/02/my-journey-creating-a-sapui5-
mobile-app-at-home-part-ii
describes how to create and activate a service in the SAP Gateway
 Fiori-like Purchase Order Approval with OData - Part II (Fiori-like SCN Part II)
http://scn.sap.com/docs/DOC-53950
describes the SAPUI5 Frontend coding, which is in JavaScript and XML
Used Eclipse(Luna) plugins:
 ABAP Development Tools for NetWeaver (as ADT)
 Eclipse connects to an SAP backend system and you can edit all ABAP classes / methods / tables...
 SAP Mobile Platform Tools, which contains the Ogee OData plugin
 SAP UI5 Development Toolkit; SAP UI5 application preview runs on the Jetty web server
 Jetty provides Web services in an embedded Java application and it is already a component of the Eclipse IDE (started as open
source project and moved in 2009 to Eclipse); https://en.wikipedia.org/wiki/Jetty_(web_server)

Steps to build sample App „Fiori POApproval“
1. Create backend ABAP code (available on Github) via SAPlink report as described in
‚Fiori-like SCN Part I‘
2. Create OData model as Entity Data Model in Eclipse and export it
3. Activate SAP Gateway as described in ‚Gateway SCN step 1‘
4. In mandant with Purchase Order data:
Create a new SAP Gateway project (described in ‚Gateway SCN‘ step 2) and import
OData Model into SAP Gateway via SEGW transaction
5. Adapt Model and create code for the data access (CRUD) methods
6. Activate service in Gateway via SPRO transaction (described in ‚Gateway SCN‘ step 4)
7. Create „Fiori“ UserInterface (UI) App with SAPUI5 Development Toolkit in Eclipse as
described in ‚Fiori-like SCN Part II‘
8. Adapt sample ABAP code to retrieve ‘real pending approval data’ from IDES system
Remark: More details, hints, remarks and recommendations can be found in the backup foils

Detailed steps to build sample App
• Import backend ABAP code (available on Github) via SAPlink report as described in
‚Fiori-like SCN Part I‘
•  SLINK project (report code must be created manually in SAP backend system )
Classes Z_MM_PO, Z_MM_POITEM, Z_MM_SUPPLIER are created
 Hint: Table Types ZMM_POITENS and ZMM_POS had to be defined in the Dictionary for successful compile.
• Create OData model as Entity Data Model in Eclipse and export it
• Install ‚SAP Mobile Platform Tools‘ plugins, which contain Odata plugin
 Hint: SCN blog says: "Start by creating a new OData project: New -> OData Development -> Service Implementation Project …”
With IDES: New -> SAP Mobile Platform OData Implementation Project -> Create New OData Model
• Activate SAP Gateway as described in
‚Gateway SCN step 1‘
 Hint: Menu structure is with 7.40 slightly different (see right figure)
 Hint: Added to AppServer profile:
icm/server_port_0 = PROT=HTTP,PORT=8080
icm/host_name_full = <full host name>

Detailed steps to build sample App cont.
• In mandant with Purchase Order data:
Create a new SAP Gateway project (described in ‚Gateway SCN‘ step 2) and import
OData Model into SAP Gateway via SEGW transaction
• Creates Classes and empty CRUD (Create / Read / Update / Delete) methods to access the data
• Remark: The IDES system contains the ABAP Front-End Server,
the SAP Gateway and the ABAP Back-End Server in one installation
(IDES ECC 6.0 incl. EhP7 Edition 2 (2015))
 Hint: Odata model was not correct in our SAP Gateway, see comment:
• Adapt Model and create code for the data access (CRUD) methods
 Hint: Code should be already available via SLINK import of frist step
• Activate service in Gateway via SPRO transaction (described
in ‚Gateway SCN‘ step 4)
 Hint: Service catalog is available at http://<server>:<port>/sap/opu/odata/iwfnd/CATALOGSERVICE/

Detailed steps to build sample App cont.
• Create „Fiori“ UserInterface (UI) App with SAPUI5 Development Toolkit in Eclipse as
described in ‚Fiori-like SCN Part II‘
• Adapt in component.js the line
var url = "proxy/http/<host>:<port>/sap/opu/odata/sap/ZPOAPPROVAL_SRV/";
with the real SAP System host, port and service name, if you have used a different one and the line
var oModel = new sap.ui.model.odata.ODataModel(url, true, "<user>", "<pass>");
with a valid SAP System userid and password
 Hint: "Target Device" does no longer exist in panel --> select Libray ‘sap.m’
• Remark: Userid and password are hardcoded and anybody knowing the URL can access the backend data!
• Recommendation: In order to get an understanding of the UI fundamentals, do the 10 exercises described in SCN “Building SAP Fiori-like
UIs with SAPUI5 in 10 Exercises”  SCN paper link
• Test: Select project, right click and ‘Run As’ ‘Web App Preview’
• Problem of sample ABAP code with IDES system
• In class Z_MM_PO and method GET_PENDING_APPROVAL the value ‘Z1’ defined for:
constants: lc_frggr type frggr value 'Z1'. "Release group from Purchase Orders in your system
did not deliver any Purchase Orders and had to be adapted:
constants: lc_frggr type frggr value 'PO'. "Release group from Purchase Orders in your system
 Hint: Check with transaction me28, which combination of Release group (and Release code) is used in your environment.
It may be necessary to adapt also value of constants: lc_released type frggr value 'C'. "Code for "released" in your system

Upload sample App and add to Fiori Launchpad
• Upload to ABAP Front-End Server
• Run report /UI5/UI5_REPOSITORY_LOAD in SE38 transaction, enter z<eclipse project name> (zVSFioriApp)
• Because we add the App to a Launchpad on the Front-End Server, adapt (SE80 transaction) in component.js the lines
var url = "proxy/http/<host>:<port>/sap/opu/odata/sap/ZPOAPPROVAL_SRV/";
with var url = "/sap/opu/odata/sap/ZPOAPPROVAL_SRV/";
and var oModel = new sap.ui.model.odata.ODataModel(url, true, "<user>", "<pass>”);
with var oModel = new sap.ui.model.odata.ODataModel(url, true);
 Hint: If your z<eclipse project> name is longer than 15 char, you can copy the project using a name with less than 15 chars
Use transactions /IWBEP/CACHE_CLEANUP and /IWFND/CACHE_CLEANUP to clean services caches and
SMICM (-> Goto -> HTTP-PlugIn -> Server Cache -> Invalidate Globally) to clean ICM cache
• Remark: SAP developer access key is needed

Add sample App to Fiori Launchpad cont.
• Configuring the App to SAP Fiori Launchpad for Intranet Deployment
• Run SPRO transaction and define a new semantic object (SAP NW, UI Technologies, SAP NW UI Services)
• Run LPD_CUST transaction and define a new Launchpad; I used role FIN_AP and defined an TRANSACTIONAL instance
• Select the new Launchpad and create a new application (VSFioriLikePOApproval) with url (/sap/bc/ui5_ui5/sap/zVSFioriApp) from SICF transaction
• Login to Lauchpad admin page: http/<host>:<port>/sap/bc/ui5_ui5/sap/arsrvc_upb_admn/main.html?sap-client=800&sap-language=EN
- create new custom catalog, steps 3.10.9-11
- add new 'App Launcher - Static' tile and enter General and Navigation parameter 3.10.17 - 3.10.19
- select the Target Mappings Icon (right to the Tiles Icon) and the press 'Create Target Mapping' on bottom right, do steps 3.10.14 - 15;
define as the action in Intent Mapping the name of the loaded App (zVSFioriApp)
 Hint: steps 3.10.12 -13 and 16 are no longer valid
• Run in client 800 PFCG transaction and create a single role, steps 3.10.20 – 25 (23: entry 'catalog provider' is now 'SAP Fiori Tile
Catalog' )
• Login to Lauchpad: http/<host>:<port>//sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html and create a new group and add the
Fiori App, steps 3.10.26 -33. Use the previously created catalog to add the Fiori App.
• Run the App… your are DONE.

Questions

SAP Gateway details
• SAP Gateway is a technology that provides a simple way to connect devices,
environments and platforms to SAP software based on market standards.
It is a set of ABAP add-ons to your existing SAP ERP system and offers an API that
gives easy-to-use access to the rich wealth of business data.
• SAP Gateway offers connectivity to SAP applications using any programming language
or model without the need for SAP knowledge by leveraging REST services and OData
protocol.
• REST (Representational State Transfer) is a style of software architecture for
distributed systems such as the World Wide Web. REST uses the standard GET, PUT,
POST & DELETE methods and other existing features of the HTTP protocol. One goal
is to encapsulate legacy systems.
• Odata (The Open Data Protocol) is an open web protocol for querying and updating
data (CRUD methods). The protocol allows for a consumer to query a data source over
the HTTP protocol and get the result back in formats like Atom, JSON or plain XML.
For a simple overview see http://scn.sap.com/docs/DOC-35472
