Automated Audit Testing for SAP Data—
Benefit or Just Another Black Box?
Stefan Wenig is chief
executive officer (CEO) of the
dab:Group, a company that
specializes in data extraction,
analysis of SAP data with
ACL and automated audit
routines. He has participated
in developing data extraction
software and is a consultant
and globally active trainer
for data analysis techniques.
Wenig has been supporting
internal audit departments in
the field of data analysis for
years.
Kyung-Hee Anita Kim-
Reinartz is branch
manager of the Dusseldorf
(Germany) office of the
dab:Group. Prior to joining
the dab:Group, she worked
for PricewaterhouseCoopers
for more than nine years.
Kim-Reinartz’s specialties are
forensic data analysis and,
notably, continuous controls
monitoring. She was a project
manager of the worldwide
continuous controls monitoring
implementation of a large
German technology company.
Automated audit testing has been discussed for
many years. Buzzwords such as “continuous
auditing” and “continuous monitoring” arose
and have been talked and theorized about. In
particular, internal auditors and public accountants
who have to cope with increasing requirements in
testing and compliance regulation are searching
for more intelligent and integrated methods of
automating testing. However, while evaluating IT
tools and ways of standardizing audit routines,
questions may arise regarding whether automation
is really the future or whether there is the risk of
creating a “black box”: a tool that makes auditors
lose certainty and trust in the results due to the
uncertainty about how the results were generated.
False positives—results that turn out not to be real
findings—may even support this reluctance.
This article discusses ways to standardize data
extraction and audit routines. It is written based
on SAP data, but this is exemplary for all complex
enterprise resource planning (ERP) systems.
Furthermore, the article discusses how to handle
increasing amounts of data and how to avoid
creating a black box.

OVERVIEW OF THE ISSUE
The methods of digital data analysis are getting
more and more important in the globalized world.
The reasons are obvious:
• External requirements such as legal or
compliance aspects require more transparency
(100 percent of transactions), preferably in real
time (immediately).
• Business processes are implemented on highly
integrated and complex ERP systems such
as SAP.
• Globalization and technological progress lead
to the generation of mass data in day-to-day
business. Having to deal with large data sets
and a growing variety of audit questions makes
time the most essential resource for auditors.
• Data extraction and data analyzing tools are
getting more powerful.
Large companies or conglomerates usually
have ERP systems, such as SAP or Oracle
Financials, in place—at least for their most
important legal entities that cover the essential
part of the transaction volume. However, instead
of hosting a clutter of systems, most companies
tend to harmonize their IT landscape and move
toward a more standardized and integrated
system. It is important to note that the databases
of ERP systems are standardized up to a point.
This means that the core table and field names
of the data, which are necessary for standardized
automation, are the same worldwide. Hence,
audit routines can be predefined and are
then generally applicable—worldwide, cross
company and, at least within the core processes,
independently of the business areas of an
enterprise. Therefore, the vendor master data
within nearly any release version of the SAP
system can always be found in the vendor
master-general section table—independent of
any parameters such as company, system and
location, as long as it is a standard SAP system.
However, for other data that cannot be located
that easily, a profound understanding of the
data and the underlying business processes
is inevitable.
Furthermore, not only auditors, but various
departments are facing more and more internal
and external requirements that occur due
to compliance issues, legal aspects and tax
regulations, for example. Abnormal transactions
have to be detected and reported immediately;
legal aspects and tax regulations require reporting
to be published/reported in faster cycles. This
shows that time and mature technology are
crucial factors to enable enterprises to meet
these requirements.
In a globalized and computerized world,
particularly well-established business processes
such as purchase-to-payment (P2P) and order-to-cash (O2C) are creating more and more data
every day.
