Geberit and SAP S/4HANA
Our vision – Simplify and Fit for the future
Operation of all SAP software solutions worldwide with
innovative, agile and safe database technology
SAP HANA to prepare for the challenges ahead of
„Big Data“.
So we can react simple, quickly, and flexible to new
standardized business requirements.
Application and processes which previously were not feasible
due to the data volume can be realized with SAP HANA.
Our focus is „future-oriented“ and less „past-oriented“.

Migration to SAP S/4HANA
• Tool SAP DMO (Database Migration Option)
• Grafical User Interface
• The same process as heterogenous system copy
• Dynamic adaptation of resources
(Number of processes, Bumber of batch)
• Data exchange over „Network Pipes“ – no disk space required
• Automatic verification of the migration (number of tables and records)
• DMO Tool is great step forward vs. the old tools ( distmon ,…)
• Migration with DMO Tool works very well

IT Know How Transfer
• First migration (BW) without „Know How“ Transfer
• Learnings:
• Often SAP HANA as „culprit“, Missing Know How from the IT
• Communication to the customer not with one „single voice“
• HCM migration with „Know How“ Transfer
• Participants all HCM IT consultants / developer
• HCM IT consultants have a good understanding how SAP HANA function
• Better communication to the customer „one single voice“
• Cooperation in the project team was excellent („Our project“)
• Certified SAP HANA administrator
• SAP Certified Technology Associate - SAP HANA
• SAP Certified Technology Specialist (Edition 2013)13

• Which SQL have the longest time
• How often is the SQL script called
• Before and after the migration
• Focussing on the Top 50
• Focussing on things which are easy to optimize
• e.g. always zero rows as a result of select

ABAP Test Cockpit (ATC)
• Two variants to check the ABAP code for
SAP HANA
• FUNCTIONAL_DB (e.g. order by)
• PERFORMANCE_DB
• Focussing on Prio 1 and 2
• Only useable for customer code
• 99,9 % of ABAP code is continue working

TDI (Tailored Data Center Integration) – Simplify Data Center
xfs Filesystem
20th. April 2015
SAP HANA Operation
20
Geberit and SAP S/4HANA
Why TDI approach at Geberit ?
• Already experiences with BWA appliance solution
• High costs
• Changes only through external technical consultant
• High space consumption in data center (whole rack)
• High TCO due to „foreign objects“ in data center
• Advantages for Geberit with TDI approach
• Only one central storage for all (Maintainability, TCO, Flexibility)
• Installation / migration can be done by internal employees
• No dependency of external consultant
• Better competition by hardware procurement („Standard“ components)

SAP HANA Operation - Capabilities
• Very robust and reliable database system
• HANA Studio
• HANA Commandline Tool HDBLCM
• Current effort of our 8 SAP HANA systems
< 1 h per week
• Import patch / new version very easy
(~ 15 min)
• No manual work (Oracle: executing a lot of sql
commands)
• Runs fully automated

SAP HANA Backup / Log Backup / Restore
• SAP HANA Backup with HP Data Protector
• With / without SAP HANA integration
• 2-phase approach
- per script with SQL to filesystem
- per filesystem backup to tape
• Runtime Backup „Memory to disk“ 20 minutes for 1 TB
• SAP HANA Logs ongoing synchronisation to a seperate storage
• SAP HANA restore with point in time recovery with SAP HANA studio

SAP HANA System Replication with SUSE HA
• SAP HANA system replication works well
• Combined with SUSE HA solution for SAP HANA
• SUSE HA certified by SAP
• Automatic takeover if system break down
• Easy to implement
• Takeover Time (1 TB Data Footprint)
• rev > 85.02 : 6 min
• 3-Tier Cluster (1-2 Tier sync and 3-Tier async)
• Bandwith usage (async Geo Cluster)
• Missing: “Shadow database” functionality
25
SAP HANA Operation
Geberit and SAP S/4HANA
SAP HANA Systemcopies incl. ABAP
• Several times performed without problems
• Can be completely done with SAP HANA Studio
• Rough procedure:
1. Start SAP HANA Backup on the productive system
2. Make Backup directory from prod. system available for target system (Mount)
3. Start Restore in SAP HANA Studio on the target system
Necessary: „Data Backup Location readapt“
4. ABAP post copy steps proceed as normal (e.g. Schema adaption in profiles)
We use PCA (Post Copy Automation) tool from SAP

SAP HANA Geberit and SAP S/4HANA
Achieved results – new possibilities with SAP HANA
• BWA and TREX are no longer required
• BW faster data load process / Fast data migration
process
• Very fast data selection
• (Until now only possible over creating temporary tables)
• Some FI functions are very fast
• e.g. Overhead calcuation for USA (from 6 h down to 10 min)
• Analysis on the level of documents FI/CO (200 million data records)
quantum jump
• Introduction of beautiful apps (Fiori)
