How To Build an Agentry based app from scratch connecting to a SAP ERP back-end – Part2

1.

Business Scenario

This How-to guide will show you step by step how to add transations, data tables and complex
tables into a very simple mobile app based on Agentry, which was previously created by following
the How-to Build an Agentry based app from scratch connecting to an ERP SAP back-end Part 1.

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, in order to extend the previously built mobile app (see Business Scenario) this
guide will take you through creating of transactions in your Agentry project to allow you to insert
data into the SAP ERP back-end as well as the creation of data tables, complex tables and finally,
the deployment of the mobile app on the SAP Mobile Platform 2.3

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 6.0.31 or higher, either as a standalone or 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 Java Runtime 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

•

Administration rights for the SAP Control Center (for the deployment of the mobile app on
SAP Mobile Platform 2.3)

•

Successful completion of the exercises described in previous guide: How-to Build an
Agentry based app from scratch connecting to an ERP SAP back-end Part 1

October 2013

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

We assume that at this point you have built a very simple mobile app that fetches the flight
schedule (or other example data of your choice from your SAP ERP back-end system) and displays
it on the mobile device/ Agentry Test Environment.
Next we will insert new screens and transactions that will allow you to choose a schedule and create
a flight booking that will be updated then in the SAP ERP back-end, adding more complexity to your
app. The booking information captured in the device is sent to the back-end, on the next transmit,
with the local Booking IDs and a unique booking ID gets generated by the backend. We will create a
rule for the generation of unique IDs, consistent with the data in the back-end, for the cases where
data is created on the mobile device locally. Then as a part of the exercise, in addition to the
transaction, we will create a new fetch definition to retrieve all the bookings created by the current
user and display it in a screen. In the example SAP ERP backend we have used for the purpose of
this guide, the Flight Booking information is stored in a table called SBOOK.
We will start by creating the backend business logic required to create a booking in the SAP
System. You can find the source code for the needed ABAP Class and a BAPI Wrapper Class in the
Appendix section of this document. In addition, we will then create the MDO object and BAPI
Wrapper configurations to link the back-end ABAP classes and the BAPI Wrapper function module
created in the ABAP system.
In the Agentry Editor, we will create the POJO, steplet, stephandler and BAPI Java classes for the
creation of the booking as well as the fetch of the bookings created by the user. We will then create
transaction definitions and their properties in the Agentry Editor as well as the required UI
elements.
In addition, for exemplification purposes, we will create data tables and complex tables as well,
which can be then tested in the Agentry Test Environment only. Please note, that the data table and
complex tables are not included in the functional mobile app, which is why they are only visible in
the test environment tool.
Finally, we will deploy the mobile app on SAP Mobile Platform 2.3

16. Click on
button
Update the below information on the Transaction Definitions
Name: AddBooking
Display Name: Add Booking

October 2013

40


17. Click on the
button
18. Next, we need to create a Rule to create an automatic BookingID for the new booking that
we create locally on the mobile device. The actual Booking ID is provided by the back-end
system, but we need to generate a local Booking ID to identify it uniquely on the mobile
device first. In the next steps, we will create a rule that will determine a unique ID on the
client.
19. Click on Properties

20. Double click on BookingID

October 2013

41


21. In the same screen, under Transaction Property Settings section

22. Change the Initial Value to “Rule - before data entry”
23. Click on the

button next to Rule:

25. Choose Add New Rule

October 2013

26. Change the Name of the Rule to – “InitialBookingID”
27. Click on

button

For the next section: Please read carefully the following instructions, prior to commencing each
step.

October 2013

43


28. Within this screen, there are three main sections. On the left side are the different rule
terms; including function and data terms that may be added to the rule. In the center there
is the current rule function within the rule and one or more fields containing the parameters
to that function. On the right, you have the structure view. This view presents the rule logic
in a tree control representing its structure.
29. To define the InitialBookingID rule logic, select the field in the center portion of the screen
labeled Rule Entry Point. This term will be the root term of the rule logic and its return value
will be the one returned by the rule to the rule’s caller.

30. In the list of items on the left, select the function tab
. By default, this will display all the
rule functions available to the rule definition. Above this list, you have a drop down control
from which a function category can be selected. This will filter the list of rule functions to
only those within that category. Change this selection now to the String category.
31. In the list of functions now displayed, double-click the CONCATENATE function. The Rule
Editor will now appear as follows:

October 2013

44


Note the center portion of the screen now lists the CONCATENATE function. Below you
have the short description for this function. Clicking the function name along the top of the
list will display the functions long description.
32. The field displayed for this function is the first parameter to the function and is labeled
String 1. Selecting the field will display the parameter’s short description, as shown in the
above example. This parameter description includes information on whether the parameter
is required or optional and the data type expected.
On the right side of the Rule Editor, note the addition of the CONCATENATE function call to
the Structure View.
33. The first parameter to the CONCATENATE function is the constant value LOCAL_. This
value can be typed directly in the String 1 parameter field. Note that as you enter this text, a
second field, String 2, will be added to the parameter fields. Also, note that the structure
view now contains the LOCAL_ text as the first parameter to the CONCATENATE function:

October 2013

45


34. The second argument to the CONCATENATE function must be the total number of current
local FlightBooking objects plus one. To determine this value additional logic will be needed.
This will begin with a call to the Conversion function FROM_INTEGRAL_NUMBER. Select
the String 2 field in the Rule Editor. Then select the category Conversion in the functions list
on the left. Within the list now displayed, double-click the function
FROM_INTEGRAL_NUMBER - making this the second parameter to the CONCATENATE
function. Since a function was selected, that function will now be the one displayed in the
middle section of the Rule Editor. Again also note the update to the Structure View:

October 2013

46


35. The parameter to the FROM_INTEGRAL_NUMBER function will be another function call to
the Math function SUM. Set this by selecting the Conversion Parameter field and then
selecting the Mathematical category in the function term list on the left. In the list of
functions now displayed, double-click the SUM function.
The SUM function will add all parameter values and return the result. For this rule the logic
needed is to add the total number of local FlightBooking object instances and add one to
that total. The first parameter to the SUM function will then be a call to the Property
function COUNT. Select the Number 1 parameter field in the Rule Editor and select the
COUNT function for this parameter from the Property category of functions.
The COUNT function counts the number of object instances in a given collection property.
This collection property is provided as the first parameter to the COUNT function. As an
optional second parameter to the COUNT function, is the Include Criteria. The term
provided as this function parameter will be evaluated once for each object in the provided
collection property. Each object in the collection for which the term returns true will be
counted. Objects for which the term returns false will be ignored.

October 2013

47


For this rule, the collection to be counted is the FlightBooking collection property. This
should then be the first parameter to the COUNT function. Select the Object Collection
parameter field in the Rule Editor. Then select the properties list by clicking the Properties
icon
found just to the right of the parameter fields. This displays a popup menu that will
include the menu item FlightBookingCollection. Select this item in the menu, which will set
this collection property as the Object Collection parameter for the COUNT function.

The rule function structure will now appears as follows:

36. The “Include Criteria” parameter field will now be enabled. This term is evaluated once for
each object instance in the collection property provided as the Object Collection parameter
to COUNT. The “Include criteria” needed for this rule is to evaluate the BookingID property
of a FlightBooking object and determine if the first six characters begin with the text
“LOCAL_”. If it does, the term provided as the Include Criteria to the COUNT function
should return true, which will then cause the object to be counted. If it does not begin with
this text the term should return false, and the object will not be counted.
The “Include Criteria” parameter, then, begins with a function call to the Logical function
EQSTR. This function compares two or more string values and returns true if they are all
equal or false if any one of its parameters is different. For this rule the EQSTR function
will compare the first six characters of the BookingID property to the constant value
LOCAL_ and return true if they are equal. To obtain these first six characters, the function
LEFT will be used, which is a String function.
October 2013

48


37. To implement this portion of the logic, select the Include Criteria parameter. Click on
, in
the list of functions select the Logical category and then double-click the EQSTR function.
This function will now be displayed in the center of the Rule Editor. Select the String 1
parameter field. Then select the String function category and select the function LEFT.
38. The Structure of the rule will now appears as follows:

39. The LEFT function is now displayed in the Rule Editor. Select the Source String parameter
field and then click the Properties icon
. The only item displayed in the menu will be
Browse Properties... Select this item to display the Target Browser screen. In the tree
control displayed, select the item Other Objects | “FlightBooking” Object | “BookingID”
Property.

40. Click the OK button to return to the Rule Editor. This property will now be the first
parameter to the LEFT function.

October 2013

49


41. The second argument to LEFT is the number of characters to extract from the first
parameter, counting from the left. Enter the value 6 in the Length parameter field. The
Structure View will now appear as follows:

42. The second argument to the EQSTR function must now be provided. To return to this
function, select it in the Structure view on the right side of the Rule Editor. The function and
its parameters will now be displayed in the Rule Editor. String 1 will be set to the function
LEFT. Select String 2 and enter the text LOCAL_ in the field.
43. Finally, in the Structure View select the function call to SUM, which will display the function
in the Rule Editor. The Number 1 parameter field will be set to COUNT. Select the Number 2
parameter field and enter the value of 1.
The InitialBookingID rule has now been defined. Review the Structure view and verify it
matches the following example:

The logic of this rule, as defined above will result in the return value of a string value
containing LOCAL_n, where n is the total number of local FlightBooking objects in the
FlightBooking collection property, plus 1.
44. Click on the
button
45. This will return you back to the BookingID property definition

4.3 Complex Tables
...

4.3.1 Create the Back-end Business Logic for the Complex Table
1.

Let us now see how to create a Complex Table in Agentry. Unlike the Data Tables, Complex
Tables have multiple fields and are meant to store large amounts of data. They are
searchable and Indexes provide the structure and search behavior to the complex table. A
complex table must have at least one index, which is the primary index (created on the field
containing the unique identifier for each record).
2. We will begin by creating the back-end business logic first to provide the values for the
Complex Table
