How to setup SAP Retail Execution (REX) mobile
Application on Android Device for SMP 2.3

Purpose

This technical document explains how to setup SAP Retail Application for Android thru a Virtual
Private Network connection. There are several methods of connecting to the SAP Mobile Platform 2.3
server device to relay server to SAP Mobile Platform server. In this scenario we are going to explore the method of
connection to the SAP Mobile Platform 2.3 server via a Virtual Private Network also known as Virtual Private Network
and access the data for the SAP Retail application(REX) application.

DESCRIPTION

SAP Retail application is used by SAP customer to perform there retail activity Sales, marketing store
visits schedulers.
We will walk thru the process and the required software to make a successful and
secure connection from the Android device via a Virtual Private Network connection. 

Required Software

1.           SAP Mobile Platform 2.3 or higher.

2.           RSA security Token.

3.           SAP 3.1 Retail Applications for Android.

4.           F5 Virtual Private Network software.

5.           Android version that is supported 4.x and above.

Assumption

·         This document assumes you have a working SAP Mobile Platform 2.3 environment.

·     You have Virtual Private Network access setup from you IT department. 

·     You IT department provided some Token creator like RSA.

·     You have the SAP Retail Execution (REX) mobile application installed and connection to SAP CRM.

Issue 1: User is not using a direct access to the SAP Mobile Platform 2.3 server
                  VIA the Relay Server or a Web server
.

·                   User needs to connect to the SAP Mobile Platform 2.3.

·         User cannot connect via WEB or relay server.

·         User needs to have a more secure connection directly to the SAP Mobile Platform server 2.3.

Solution

In order do that you need to configure Your Android device to connect via a
Virtual Private Network connection


Post SAP Retail Execution (REX) mobile application Deployment on SAP Mobile Platform 2.3:

1.      Go to Google’s Play Store

2.      Search for SAP Retail Execution(REX)

3.      Select install to download and install the application.

                       

Figure 1

If WIFI/3G or 4GL connection is used to the SAP Mobile Platform 2.3 server to connect
remotely, you will need the following applications installed on the Android device:

1.   F5 Edge Client Virtual Private Network Software.

2.  RSA SecurID software.

3.  SAP Retail Execution(REX)

4.  Tested Samsung Galaxy S3,S4 and S5, Android 4.4.2  

You will need to go to the App store and search for RSA Security ID and
F5 Edge Client.

Figure 2

The above screen shot is showing all the SAP application that are installed
as well as the RSA and F5 Edge Client. To reduce the cost we recommend
a WIFI connection if possible in our test we did you WIFI and the Application
was also tested using 4G LTE.

After installing the required software you’ll will need to

1.   Generate a password using the RSA.
2.   Virtual Private Network in to the SAP network using your ID and RSA Token.

Generating a SecurID

Figure 3

Here is a screen shot for the RSA SecurID here you would enter
you pass code to generate you six number code.

Figure 4

The above screen is from the Android Play Store showing a generated
Token Code. Note the above number is not real and is not use full and
is only an example. 

Starting the Virtual Private Network Client

The next step is to start the F5 Virtual Private Network Client.

Figure 5

NOTE:It is up to each company to set up there users RSA Token and the F5 Edge
Client Virtual Private Network. We do not cover those steps in this write up.
For SAP employees refer to SAP IT mobility options.

1.    Add your Server that allows a connection for Virtual Private Network access.

2.    Add you user name.

3.    Add the generated RSA Token you generated in RSA.

4.    Tap on Login to start the Virtual Private Network connection.

Established Virtual Private Network Connection

Figure 6

In the above screen shot note the KEY icon on the top left hand side.
This is indication that we now have a successful Virtual Private Network
session and we can now continue and start the SAP Retail Execution(REX).

Figure 7

After installing SAP Retail Execution

1.      Launch the SAP Retail Execution(REX) application from the icon on your device

2.      Accept the license agreement tap Accept.

Install options for SAP Retail Execution

Figure 8

There are 3 options for SAP Retail Execution(REX) configuration:

Ø     Demo Edition: to preload some sample data

Ø      Setup Connection: to setup with SAP Mobile Platform 2.3

Ø      Afaria Setup: To configure the enrollment with Afaria

SAP Retail Execution(REX) Connection setup options

Figure 9

We need to add the SAP Mobile Platform 2.3 server address the farm ID

UserID and password the port number and security Configuration
the address and port number in this example need to be 100 %
Correct
because we will be directly connection to the SAP Mobile Platform  2.3
server thru the Virtual Private Networkconnection so everything needs to be true.

Registration Process with the SAP Mobile Platform Server

Figure 10


During the Connection phase and Sync operation you can see that the
SAP Retail Execution(REX) application is connecting via  the TCP/IP
address you have entered.

Adding your PIN Number

Figure 11

The PIN number is used for security on the mobile SAP Retail Execution(REX) Application
in order to connect again after you have completed all the steps and closed the application.
Open it again to use the application. It will ask for the PIN number. Otherwise the application
will not make an attemptto connect to the SAP Mobile Platform server and CRM server.


Remember you PIN number, because each time you launch the SAP Retail Execution(REX)
application the first thing it will ask for is the PIN number.
It will not connect to the SAP Mobile Platform 2.3 server without it.

Configuration of the CRM Credentials

Figure 12

In our example we need to add the CRM user name and password.
This is not the same as the SAP Mobile Platform 2.3 user name and password. If
you are using No security on the SAP Mobile Platform 2.3 server

In order to configure LDAP to support SAP Retail Execution(REX), we need to have in place

Ø      A domain for the SAP Retail Execution(REX) application ( i.e REX2014  )
You create that in the SAP Control Center

Ø    A security profile created for the SAP Retail Execution application ( i. e REX2014)
You create that in the SAP Control Center
And LDAP provider security profile in SAP Control Center A CRM user in the SAP back-end

Ø     The CRM user ID and password, MUST BE IDENTICAL to the LDAP,otherwise the data sync will fail

After you add you CRM user and password the Application will then

Start the Sync processing. First the application will register the application

Client Device ID and User ID

Figure 13

At this point the SAP Retail Execution(REX) application will start the process
to connect to the SMP 2.3 Server to register the User and the device ID.

Connecting and Synchronization processing

Figure 14

You will see the notification bar change and will let you know the progress of the Sync
operations to the SAP R3 CRM.

Don't interrupt the Sync it may take one to two min so be patient and  let it complete the
first time may take a little longer
due to the fact that the local database will get updated
After the first initial SYNC the next SYNC will go much faster.

Figure 15

Once the SYNC operation is completed you can now go thru the menus and select the
different options. Above are two different screens showing some of the really cool options
the REX application provides.

Figure 16

To verify that the user is registered and the application is in SYNC we can log in to the SAP Control Center
go to applications ->user connections and we can see in in figure 16 the details of the user.

NOTE: If the user removes the application from the device, they also need to be removed from
the SAP Control Center otherwise the user will not be able to reregister they will receive an Error
the Device ID is already in use.

Summary

The Retail Application with the combination for the SAP Mobile Platform works great together If

your origination is need of Retail application I would highly recommended looking at REX and the

SAP Mobile Platform. As you can see in this write up there are a number of way to connect to the

SAP Mobile server, WEB Server, Proxy Server and a direct connection thru a

Virtual Private Network connection. In all cases it is possible to find a solution for the end user to

establish a connection to the SAP Mobile Server in order to consume your data. 

Considerations are your IT department need to have the networks configured for SSO,

Virtual Private Network access in order for this example to work.
