Pressure to create data protection conformity persistently increases in the context of the
new Data Protection Act.

 Fines range from EUR 50.000 to 300.000 per
violation (violations can be cumulated)
 Deletion of personal data acquired and processed
for a particular purpose must be deleted as soon
as the knowledge of this data is no longer required
for that purpose.
 Information: The responsible body must provide
the person concerned, on request and free of
charge, with information on all stored data with
reference to persons, recipients and the purpose
of the storage.
• (changed) Fines range up to the higher of 20 M€ or 4% of total
worldwide annual turnover of affected companies.
• (new) Right to data portability (Art. 20 GDPR)
• (new) Privacy by Design and by Default (Art. 25 DS-GVO)
• (changed) ‘Right to be forgotten’ (Art. 17 GDPR) far exceeds the
current right to deletion.
• (changed) Obligations regarding transparency and disclosure (Art.

The use of personal data in energy management systems leads to four concrete fields of
action.
Uses of personal data in energy management IT systems:
Fields of Action
Comprehensive real data in
project / test and training
systems
Historical data in productive
systems
Extensive database of process
execution
SAP Test, Training and/or project
systems are built on a complete
copy of the production system.
The access to data is possible at
any time fully and partially
depending on the authorization.
After the processing of data,
contracts or service contracts,
customer data is passed on to new
service providers.
The historical data remains current
and in the respective production
systems.
Processes for acquisition and
contract processing generate data.
The use of this data is legitimate for
the respective purpose.
After the process has been
completed, the data is still available
without restriction
Test and project system only
with anonymous data
Personal data after expiration of legitimation to be deleted
Anonymization training and
testing system
Delete historical data

Customer requests to provide
information
Requests for information about the
affected persons concerning the
storage and processing of their
personal data.
Information is currently available as
a manual process and information
can only be provided with high
effort and usually not in the legally
prescribed format.

Customer requests to provide
information
Requests for information about the
affected persons concerning the
storage and processing of their
personal data.
Information must be provided in a
structured, electronic form with the
following specifics; the place, the
reason and the recipient as well as
the duration of the storage / deletion
criteria.
Comprehensive real data in
project / test and training
systems
SAP Test, Training and/or project
systems are built on-a complete

Extensive access to data is
possible.

• Project / test systems are built as a copy of the productive system.
• The authorization structure in this system is usually not very strict.
• Both internal and external employees have extensive access to data and processes.
• Technical data access / direct database access is often possible.
• Training systems are built as a copy of the productive system.
• The authorization structure in this system is usually mediocre, depending on the training.
• Usually only internal employees are trained.
• Technical access to the data is usually not possible.
• Quality assurance systems are built as a copy of the productive system.
• The authorization structure in this system is usually very strict.
• Usually, internal employees have access to these systems.
• Technical access to the data is usually not possible.

Personal data may not be used for a test execution of IT software.
Comprehensive real data in project, test and training systems
"[..] Software and IT procedures are to be checked
with systematically developed case constellations
(test data, no personal data) according to a test plan,
from which the desired result emerges.
Mass tests can, if necessary, be carried out with
anonymized original data after approval and
specifications of the competent authority.
The approval of the responsible authority for the
anonymization of original data and all test results
must be documented in a revision-proof manner.

Challenges & Solutions
Known challenges in pseudonymization
Common Challenges Solutions
Networked Systems
Coherent systems must also have a synchronized database after pseudonymization.
Completeness
The pseudonymization must take all personal data into account (customer
developments and add-ons).
Speed
The performance of a system changeover / anonymization is based on the deciding
factor of feasibility. The pseudonymization must have no noticeable influence on the
established processes.
Sustainability & Complexity
An SAP system landscape is subject to constant change. Data structures are modified
and new data structures are added which may contain data with a person reference.
External Systems / Interfaces
Interfaces to non-SAP systems are subject to increased attention in the context of
pseudonymization. At this point, problems can arise in the testability / functionality of
the processes.

 Rule-based data scrambling
 Single systems can be pseudonymized or
anonymized.
 Central control via a control system possible
(SOLMAN)
 Rule-based pseudonymization
 System landscapes or individual systems can be
selectively or completely pseudonymized.
 Templates for ERP / CRM / HCM / IS-U
 Central control of any SAP system
 Rule-based pseudonymization and anonymization
 Individual systems can be selectively
pseudonymized or anonymized.
 Templates for IS-U / CRM
 Central control of any SAP system

The data anonymization can be
performed centrally from one system
for all connected synchronously or on
each system asynchronously.

Practical Demonstration of a Pseudonymization
Connected System
Customer-Specific
Developments
All Personal data must be taken into
account. This also affects proprietary
developments and add-ons.
Sustainability
The permanent changes to the
system landscape / data structures
must be taken into account in the
solution without carrying out
continuous development activities.
Storage tables can be supplemented
easily and flexibly.
Performance
System anonymization within a
quality or test system must be
achievable in a minimum runtime
frame.
