How To Build an Agentry based app from scratch connecting to a SAP ERP back-end – Part 1

1.

Business Scenario

This How-to guide will show you step by step how to create a very simple mobile app based on
Agentry, which will fetch flight information from an SAP ERP back-end and display it on the mobile
device/Agentry Test Environment.

2.

Background Information

The Agentry technology also allows building custom mobile apps and this How-to guide is meant to
show how you can start the scratch with building a metadata driven app using the Agentry
technology and connecting to an SAP back-end.
The example we are providing here is aiming at building a simple mobile app that fetches data from
an SAP ERP back-end and displays that data on the mobile device. At the end of this guide, you will
be able to see data from the back-end in your mobile app simulation in the Agentry Test
Environment tool.
For that purpose, this guide will take you through the installation of the software components, the
creation of an Agentry project in the development environment, the required ABAP classes in the
back-end and the required Java classes in the Agentry project to be able to fetch the data from the
back-end, as well as the UI elements in the Agentry project to build the mobile app display of data.

3.

Prerequisites

In order to be able to follow all the steps mentioned in this guide, you need to have the following in
place:
•

An installed and running SAP ERP system that you can connect to and for which you have a
developer key

•

Agentry SAP Framework Administration installed in the SAP ERP back-end you intend to use
in this exercise

•

Access to the installation file for Agentry Server 6.0.XX as a standalone or Agentry Server
6.1.03 as part of the SAP Mobile Platform 2.3*
*If you have the SAP Mobile Platform 2.3, in order to be able to develop a new Agentry
based app, you will need the SAP Mobile SDK as well, which will include the Agentry
Development Server, the Agentry Editor plugin, the Agentry Test Environment

•

Access to the installation file for Agentry Server Administrator 6.0.31 or higher

•

Access to the installation file for Agentry Editor Plugin (either individually downloaded from
the SAP Service Marketplace or as a part of the SAP Mobile SDK 2.3)

•

Installed Eclipse Indigo 3.7.2 on the machine where you intend to do this exercise

•

Installed JDK 1.6 or higher on the machine you will be using for this exercise

•

Valid license keys

•

Administration rights on the machine you’re working on

You can install the Agentry Server, the Agentry Editor and the Agentry Test Environment
components on the same machine.
A previous understanding of the Agentry technology is a must for this How-to Guide.
ABAP and Java understanding is recommended.

Step-by-Step Procedure

First we need to setup our development environment and install the Agentry Development Server
as well as the Agentry Editor.
Next we are going to create a new Application Configuration in the Configuration panel available in
the SAP ERP back-end. This will be your application configuration which will be used by your
Agentry server, to know which MDO’s/BAPI Wrappers in the backed ERP system are going to be
used. By doing this your Agentry server uniquely talks to your application configurations and in turn
your own MDO Objects and BAPI Wrappers. Once this step is done you will be set to create you first
Agentry mobile application connecting to an SAP ERP backend.
Then we will create a mobile application to display a list of Flight schedules with the following
information Flight date, Airport From, Airport To, Carrier ID. In the example SAP ERP back-end we
are using, the information needed for these 2 screens are available in 3 different tables SFLIGHT,
SPFLI and SCARR. You need to create the backend business logic to get this information and an
Agentry app with definitions for the Fetch mechanism which will bring the data from the back-end
system, as well as the UI elements to display this data on the device or the Agentry Test
Environment. In addition to this, you will need to create in your Agentry Project the Java Classes
required to call the SAP back-end and provide the information to your Agentry mobile app.
The business logic and BAPI Wrapper is made available to you by a template class
(Z00_GET_FLIGHT_SCHEDULE) and template BAPI Wrapper
(Z00_BAPI_GET_FLIGHT_SCHEDULE), for which the source code is available in the Appendix
section of this document.
Once the business logic is created and the fetch mechanism is built you can test your mobile app by
displaying the example data from the SAP ERP back-end in the Agentry Test Environment.

Development Server will be installed as a Windows Service.
For the purpose of our exercises and ease of use, we will not use this option,
because we will have to restart the server several times.

12. Installation begins and may take a minute or so to complete.

13. In some cases you might be prompted with the above message. Click on Ok, this is because
the server tries to install a VC runtime and you might get this message if the VC Runtime is
already available in your system and the installation is unable to overwrite.

65. Notice the class variables that are available in the FlightSchedule.Java Class. These
variables will be used in creating the Object Properties for our FlightSchedule Object
automatically
66. Now we are ready to create the Object Properties for our FlightSchedule Object using the
Java File
67. Switch back to Agentry (Properties) Perspective by clicking on the
tab in
the upper right hand corner (or by going to: Window > Open Perspective > Other > Agentry
(Properties)
68. Within the Agentry Perspective, locate the Class Constructor for FlightSchedule
Class(Class constructor is the one with the C icon)
69. Right-click on the Class Constructor and select Agentry Connector Studio -> Object Wizard,

for which we are about to create the Object and Properties.

71. Click Next

October 2013

55


72. You will notice that the ScheduleID field is read-only. This is because, previously, we
created this field manually.
73. Review the Object Name – FlightSchedule, which is the Object that is already created and
the Agentry Connector Studio will create the Properties listed for the Object FlightSchedule
The Agentry Connector Studio is also capable of creating an Object along with its
associated Properties which we will see later in other exercises.
74. Click Next

75. You will notice that the Parent Object is automatically set to Main Object, and a Collection
called Flight Schedule Collection will be added as a Property to the Main Object. The Key
Field is already set to ScheduleID (we created this Property manually and set this as a Key
Property)
October 2013

56


Even though the Key Property dropdown is greyed out, you could choose a different
property than the suggested one, if needed.
76. Click Next

77. We are not going to Create the Add, Edit, and Delete Transactions here, so uncheck all
three Step and click Next

78. We will manually create the Get Step, so uncheck the “Get” Step and click Finish
79. Click on the FlightSchedule Object and view its Properties

Create the Business Logic in the SAP ERP Backend

Until now we have created Objects and Object Properties. Next we will create the business
logic required to populate the Objects from the SAP ERP Backend System
As a pre-requisite for creating the business logic required to fetch the Objects from the SAP
ERP, we will create Package and Function Group in SAP ERP
1. Logon to SAP ERP with the user and password provided to you by your Instructor
2. Launch Transaction /nse80

3. Click on
from the left side of the screen
4. Choose Package from the dropdown and enter Name ZXX_FLIGHTBOOKING (XX being the

11. The GET Method contains the business logic to retrieve the flight schedules from the
SFLIGHT table
12. The GET_DATA_FILTER_LIST Method defines a filter that controls the data that will be
retrieved by the GET Method
For example, we can set a Filter at the application level to retrieve only flight schedules
of LH-Lufthansa or UA-United Airlines etc.
