Quality, sustainability, and future readiness

1

Agenda
 Quality
 Customer Service
 Innovation
 Low Cost
 People

2

Quality - Performance
 Methods are the fastest running code, so performance
is better, (but, you can always write bad code, so this is
provided the method is written correctly)
 OO is more granular, so the code you write has many
more options, you can write it at a finer level, and do
more with it that you just can’t do with procedural
code

3

Quality - Maintenance benefits
 ABAP Objects
 better supports separation of concerns
 data encapsulation
 explicit instantiation
 inheritance
 interfaces
 event-driven flows
 cleansed syntax
 Access to new SAP technologies
 Add additional flexibility of inheritance and encapsulation
which can reduce development times in subsequent projects
and increase the ease of maintenance and stability of
programs.

4

Customer Service
 Web Driven User Interface
 Ease of use
 Once we have our repository – quicker development
time
 Better requirements for user interfaces – Design the
screen that they will see while in the meeting

5

Innovation – OO Technologies
 Global classes are heavily used for implementing business layer
functionality
 Local classes should be used for local modularization (instead of
forms)
 BADI Implementation
 SAP List Viewer
 All other SAP Controls
 Web Services
 ICF services
 BSP
 FPM
 All programs that are based on one of the former UI technologies
 RTTS (which is important for dynamic programming)

6

Innovation OO Technologies
 SOAP
 ABAP Proxy
 Enhancement Spots
 ABAP Eclipse for HANA programming
 All new technology

7

Innovation / Cost –SAP Platforms
 All these platforms are built around OO. It would cost
money to support without internal resources.
 SRM
 EWM
 RPM
 EMCS
 Other systems we have now???

8

Low Cost / Innovation - OO
Mandatory
 OO is mandatory to take advantage of the great stuff
out there in code exchange like abap2xlsx, abap2gapps,
abap2qrcode, ZSAPLINK
 WDA and CRM UI is the strategic UI technology for
SAP, so basically you say eventually everything is going
to be in WDA whether or not you like it, so start
getting ready now.

9

Low cost - Maintenance
 Official SAP programming guidelines by Horst Keller
 Prohibits many obsolete statements and additions
 Requires implicit statements to be explicit
 Detecting and preventing potentially incorrect data handling
 Data Encapsulation
 Explicit object instantiation
 Improved code reuse by inheritance
 Standalone interfaces
 Explicit event raising and handling
 Provides access to newer technology

10

Low cost - Maintenance
 About 35% of running programs in ECC have objects.
 Number of objects having the object type CLAS or
INTF=> 125000 + 39000 = 164000
 Look for number of objects having the object type PROG
=> 302000
 More OO in each EP / version

11

Low Cost - Classic programming
 Classic programming is still needed for:
 RFCs
 ABAP Dynpros
 Certain Frameworks

12

People - Who?
 Everyone
 Consultants
 Employees
 Customers

13

People - Development
 Current SAP Development Training courses
 BC100 – Basic ABAP Techniques including structured
programming – 2 Days
 BC400 – ABAP Workbench foundations – 5 days objects
and all the next courses in development assume you
know objects (Programming reports ALV OO)
