PREFACE
Writing a book about SAP and the programming language developed by SAP
requires first of all providing consistency and semantic integrity with the use of
the most convenient Turkish terms for localizing those English ones which have
never been localized into Turkish before. Successfully doing this means being
the pioneer and it is a hard task to perform.

The literature shows that providing clear concepts as well as a common
language with syntax and semantic integrity was the primary obstacle to
overcome for the first SAP founders and programmers who developed SAP. For
instance, providing conceptual consistency, distinction of terms and semantic
integrity from the first design and architecture to functional logic system, as well
as launching new products and services without contradiction with the legacy
concepts and definitions requires high volume of time and resource
consumption. SOA - Service Oriented Architecture  Newly developed service
oriented web based SAP architecture is the most striking example for this. In
SOA application, in order to define and implement all business processes and
structural characteristics of an enterprise as well as purposes and tools of target
hierarchy on web basis, re-definition, re-naming, improvement and
simplification of the legacy concept and definition conventions are needed.

Within this crisis and unemployment period where a global demand shortage is
being experienced and investment banking is corrupted, in order to enable the
consumers to spend money again by trusting in future, in decision taking
mechanisms where the productivity growth and profitability are based on
efficient resource planning as well as business intelligence and in business
management, new resource usage and price balance between goods/services and
cash flows in the real estate, energy and finance markets should be established
as soon as possible. In this highly ambiguous environment, using SAP BW BI as
well as ABAP and Java Platforms together with the related programming
language means obtaining the most important comparative advantage from the
point of view of both employers and consultants/programmers who are working
in the field.

It is difficult to be a SAP Consultant without ABAP knowledge. Although
generating ABAP Code have been facilitated by the efficient use of graphic
menus with the help of object based programming tools newly developed by
SAP such as drag & drop methods in AWB and WAD that are opened through


                                         1
RSA1 and SE38 commands, it is not possible to check the correct usage, to
discover the error and to correct it immediately without reading the ABAP
Code.

Yener T端rkeli submits his several years market experience and efforts to SAP
and ABAP users as well as beginners who wish to learn SAP ABAP. Since this
is a first in the relevant field in Turkey, additions, corrections and depending on
the demand, new developments and improvements would be introduced in the
following editions upon dialogue with the readers.

My book Enterprise Resource Planning and Business Intelligence that I plan
to complete the writing process in February 2009 handles complementary
subjects with Mr. Yener T端rkelis valuable book My ABAP Consultant. I
especially recommend "My ABAP Consultant since it is a first in the field and
I believe it will be beneficial both in theoretical and practical terms to all SAP
Users, Consultants and Programmers.
