Background
•
•
SAP HANA is fundamentally a database and not “magic”
However, it provides major benefits in terms of:
 Landscape simplification
 Speed of queries and data access
 Simplification of environment management
 Long-term lower Total Cost of Ownership (really!)
 An enabler of the next generation of ERP and data warehouses
for real-time access, model simplification, agility, and support
for Big Data volumes
HANA projects should think big and act small. After the installation project
is ended, what do you plan on deploying in terms of new capabilities?

Tables Inside HANA Viewed Using HANA Studio
We can view table definitions and data inside HANA Studio. This
includes SAP BW tables, ERP tables, and tables we created ourselves.
6
Creating an Attribute View
•
•
An attribute view is normally used to expose
master data to the front-end tools, such as those
found in the SAP BusinessObjects tool suite
They can also be accessed by any ODBC/JDBC
compliant third-party tool
A view is a logical way to
simplify the complexity of
a database for users who
need access
7
Adding Table Joins to More Customer Information
In this example we are adding more information, such as country and
language, to the view. This data was stored in other tables, but we want to
make it easy for our users to access without database knowledge.
8
Applying a Filter to an Attribute View
Sometimes we don’t want to give
users access to all the
information, and we can “hard
code” a filter in our view
In this example, we are limiting the
view only to valid customers
9
Deciding What Users Should See and Assigning Key
Attribute
Sometimes, we don’t
want to give access to
everything available in
the tables.
We can then decide
what fields are
available to the users
(these are flagged
with orange balls)
10
Validate and Activate a View
•
•
HANA also provides a
validation of each view to
make sure it is correctly
defined and meets all
standards before it is
activated
Once activated, you can
expose it to your target
users via standard HANA
security
11
Creating an Analytical View
•
An analytical view is a way
to join master data and
transactional data together
for simple access
12
Data Foundations and Logical Joins
•
•
The resulting
models in the
view can be
further refined by
controlling what
is exposed to the
end users
We call the
transactionoriented data the
“data foundation”
and can link
other attribute
views to this
13
Adding a Calculated Field to an Analytical View
•
•
•
•
We can also create our
own calculations in the
view
For example, we are now
creating a new field called
“net revenue”
This we have defined as
“revenue” minimum
“discount”
Complex math functions
can be called and custom
coding can also be added
14
Multi-Currency Handling
•
•
If we have loaded other
currencies to the
system, we can also add
these capabilities to the
view
I.e., in the advanced
section of the calculated
column, we can flag the
field as using a source
and a target currency
and let the system take
care of the translation
15
The Resulting Analytical View
Views are found in the navigator section of the modeler inside HANA Studio. You
can preview the results and also view metadata about the view and its definition.
16
Deploying Analytical View in BO Explorer
The SAP
BusinessObjects
tools can easily
access the views
inside HANA
Here we are building
an Information
Space in SAP
BusinessObjects
Explorer that is
accessing the view
we just created
17
Accessing the View Through an Information Space
All the fields we
exposed and
created in our
analytical view are
now displayed here
for easy access by
the SAP
BusinessObjects
Explorer tool
We don’t have to
do any more
development work!
18
The Result in SAP BusinessObjects Explorer
Users can now navigate the
HANA views at sub-second
speed without having to
develop anything further
More complex analysis can
also be added via other SAP
BusinessObjects tools
19
HANA Development Demo Step-by-Step
In this demo, we will look at our example in more detail and also see how to load data
to our HANA system using SAP Data Services
20
SAP HANA — Some of the Front-End Connections
All SAP BusinessObjects tools can be
connected to SAP HANA. You can even
access HANA using Microsoft Query and
other tools.

New Business Content Optimized for BW on HANA
SAP has developed
specific, new content for
BW on HANA
This takes advantage of HANA
optimized transformations,
consolidated InfoObjects, more
line item details, and in some
cases leverages the BW models
and the HANA models in
combined scenarios
For those “green fielding” a HANA implementation, or planning to develop analytics
in these areas, serious consideration should be spent on leveraging this new content
23
SAP HANA and BW 7.4
•
•
BW 7.4 on HANA introduces the Smart
Data Access that allows us to create:

Virtual table (real-time) links to a
source system

CompositeProviders to link BW DSOs
and “native” HANA views and tables

Create a flexible logical EDW that can
be remodeled without moving data
We also get a shared modeling tool
based on Eclipse
Using the new Operational Data Provisioning (ODP) we can also remove the
need for PSAs, thereby simplifying data architectures and reduce data latency24
SAP HANA and BW 7.4 — Open ODS View
•
•
For BW 7.4, we get a new object called an Open ODS View
This new object allows us to include external data models in BW and
to query BW and non-BW data in a single BEx query
In the past, BW has been criticized for the complexity to integrate non-BW data in an EDW.
The new Open ODS view and the new CompositeProvider solves most of these issues.
25
Cool New Feature: Automatically generate HANA
Models from BW
•
•
•
•
You can now automatically
create new HANA models
based on InfoCubes and DSOs
in BW
The generated HANA views
access the data in the
InfoProviders
All HANA View capabilities are
available for the BW data
BW Security in leveraged, and views can be accessed by tools such
as SAP BusinessObjects Explorer, SAP Lumira, and other SAP
BusinessObjects tools
In addition to the BW model, import in the HANA modeler, this
functionality leverages the existing metadata in BW to create new views
26
Some of
the
features
in BW 7.4
are HANA
specific
Others are
available
for
traditional
RDBMs
This is an
overview
of what is
available
for HANA
and nonHANA

Pre-Steps — Cleaning up Your BW System
•
You can save significant amounts of work by doing a
cleanup effort before you start your HANA migration
or BW upgrade project
•
For example, an international company had a BW system with over
108 TB, with only 36 TB in the production box and the remaining
data on their Near-Line Storage (NLS) solution
•
This cleaned BW system saved them potentially millions of dollars
in hardware and HANA licensing costs
It is not unusual to reduce a BW system
size by 20-30% during a clean up effort
33
12 Pre-Steps — Cleaning up Your BW System
1.
2.
3.
4.
5.
6.
Clean the Persistent Staging Area (PSA) for data already loaded to DSOs.
Delete the Aggregates (summary tables). They will not be needed again.
Compress the E and F tables in all InfoCubes. This will make InfoCubes
much smaller.
Remove data from the statistical cubes (they start with the technical
name of 0CTC_xxx). These contain performance information for the BW
system running on the relational database. You can do this using the
transaction RSDDSTAT or the program RSDDSTAT_DATA_DELETE to
help you.
Look at the log files, bookmarks, and unused BEx queries and templates
(transaction RSZDELETE).
Remove as much as possible of the DTP temporary storage, DTP error
logs, and temporary database objects. Help and programs to do this
are found in SAP Notes 1139396 and 1106393.
34
12 Pre-Steps — Cleaning up Your BW System (cont.)
7.
For write-optimized DSOs that push data to reportable
DSOs (LSA approach), remove data in the writeDSOs. It is already available in higher level objects.
optimized
8.
Migrate old data to Near-Line Storage (NLS) on a small
server. This will still provide access to the data for the few users who
infrequently need to see this old data. You will also be able to query it
when BW is on HANA, but it does not need to be in-memory.
9.
Remove data in unused DSOs, InfoCubes, and files used for staging in
the BW system. This includes possible reorganization of master data
text and attributes using process type in RSPC.
35
12 Pre-Steps — Cleaning up Your BW System (cont.)
10.
You may also want to clean up background information stored in the
table RSBATCHDATA. This table can get very big if not managed. You
should also consider archiving any IDocs and clean the tRFC queues.
All of this will reduce the size of the HANA system and help you fit the
system tables on the master node.
11.
In SAP Note 706478, SAP provides some ideas on how to keep the
Basis tables from growing too fast in the future; if you are on Service
Pack 23 on BW 7.0 or higher, you can also delete unwanted master
data directly (see SAP Note: 1370848).
12.
Finally, you can use the program RSDDCVER_DIM_UNUSED to delete
any unused dimension entries in your InfoCubes to reduce the overall
system size.
36
A Tool to Help to Migrate and Clean Up
•

SAP has created a cockpit to:
 Clean up the SAP BW
system
 Reduce system size
 Conduct pre-checks
(readiness checks)
 Size the system
 Find sub-optimal code (i.e.,
transformations)
 Look at table distributions
and loads
There are over 235 tests in
this tool as of version 3.0 in
March 2014
These tools are thanks to SAP’s Marc Bernard
and his team at SAP Labs Canada
37
Tips to Make the Database Smaller
•
•
•
•
Use write-optimized DSOs as first level data stores. These can
easily be off-loaded out of main memory in HANA and save you
money.
Keep your Persistent Staging Tables (PSA) clean. BTW: The PSA is
often not needed at all in BW 7.4.
If you are on BW 7.3 Service Pack 8 and HANA with at least Service
Pack 5, the write-optimized DSOs and PSAs are flagged as “early
unload” from the HANA memory. This will help you keep the system
smaller and require less memory.
You can also flag other InfoCubes, DSOs, tables, and partitions as
“not active”. If you do so, they will only be loaded into memory when
actually required.
The sizing program in SAP Note 1736976 takes these size
savings settings into account when sizing your HANA system
38
Clean up of SAP BW Before Migration — Tool Support
•
•
Areas of database size reduction
 Delete application logs
(and/or archive)
 Delete job logs
 Delete OLAP and planning statistics
 Delete data from the change log
 Delete requests from the PSA
 Delete master data and texts for a
characteristic
 Delete data selective
 DTP temporary storage reduction
 Archive IDocs
 Archive request administration data
The Technical InfoCube (0TCT_C25)
contains information on large tables that
can be candidates for further reduction
For more details on how to get sizes down and what each of these
areas mean, see the Intro to HANA book, Chapter 5

BW Transformation Finder
• Some
custom data transformations in SAP BW can be sub-optimally
written and have negative impact on HANA performance
• The
BW Migration Cockpit provides a tool to help you identify them
This part of the tool can be run on
SAP BW 3.5 or higher. See SAP Note
1908367 for more details.
41
Code Inspector and Analyzer for ABAP in BW
•
After you have found the codes you
searched for, you can analyze the code
to see if improvements can be made to
make it even faster in HANA
•
You get a lot of additional information in
the log (scroll to the end for some great
ideas of how to optimize the code)
This tool also runs on all BW releases
3.5 or higher (see SAP Note 1847431)
42
System Migration Optimization and SUM
•
The Software Update
Manager (SUM) was
enhanced and now also
contains an option called the
“Database Migration Option
(DMO)”
•
The DMO allows you to
combine the BW upgrade,
Unicode conversion, and
other tasks that are often
required, as well as the
actual HANA migration in
one interface instead of two
“projects”
You can use the DMO if your are on minimum
SAP BW version 7.0 and have applied Service
Pack 17 (see SAP Note 1799545)
43
BW 7.4 DSOs and Re-Conversion of DSOs
•
•
BW optimized DSOs were reccomended in 2013.
HANA optimized DSOs were available for BW 7.3.
As of February 2014, SAP reccomends that you do not to do any optimization of
DSOs and actually convert back to the old DSOs for SAP (Note: 1849498)
44
Converting InfoCubes and/or Data Flows
•
•
While not required, InfoCubes can be
optimized further for HANA performance
This basically means “flattening” the
data structures and removing the
dimensions in BW from the physical
layer (they still look as if they exists)
Many refer to this optional step as a “functional migration” and do this after the HANA
migration has been completed, often as a separate initiative (see SAP Note 1849497)
PS! Optimization of DSOs are no longer reccomended
45
Converting InfoProviders and/or Data Flows
•
•
•
•
To help you, the SAP Migration Cockpit
also allows you to migrate your data flows
from 3.x to Data Transfer Processes
(DTPs) as used in versions 7.0 and higher
If you convert the data flows you get
better automated data package DTP
optimization, which loads data faster into
HANA.
You can also simulate the data flow before you do the real
conversion. When doing so, data is loaded for both versions
(3.x and 7.x) of the dataflows and the results are stored in
cluster tables. The data is then compared to verify that the
dataflow after migration calculates the same data as it did
before migration
Since the differences are displayed separately, you can
analyze the results and changes in details
46
The Application Specific Upgrade (ASU) Toolbox
•
Once you have completed the
SAP_BW_HOUSEKEEPING
and the
SAP_BW_BEFORE_UPGRADE
task lists, you can start the
ASU schedule manager and
prepare the environment
•
While there are some
overlapping tasks in these
task lists, you are required to
complete all tasks listed as
“obligatory”
•
You start the upgrade by
executing the transaction
/ASU/START (see SAP Note
1000009)
The Direct Migration Option (DMO) for
upgrading BW and moving to HANA at the same
time also uses these task lists and the ASU
Toolbox. DMO is an option in the SUM tool.

Direct Migration Option (DMO)
•
During the upgrade from BW 3.x to
version 7.0 many companies
decided not to complete Unicode
conversions, security conversion, and other recommended steps
•
Since these are now required for the BW 7.4 and the subsequent
migration to HANA, some companies are planning first to do the
upgrade and then do a migration project. That is a mistake!
•
With the new Direct Migration Option tool you can accomplish both
the 7.4 upgrade and the HANA migration in one step.
DMO is a key option in the Software Update Manager (SUM), for those with
older, out-of-date, BW systems that want to migrate to HANA.
49
Creating a DMO Migration Run-Book
•
•
•
The best way to approach this is to start with
the sandbox system and create a runbook with
step-by-step lists on how each problem and
software task are created. It is not unusual to
have a 90-100 page word document with screenshots and
documentation at the end of this first migration.
The “runbook” is the key to success. You should build on this when
you migrate to the Development and then the QA and the Production
systems
DMO started supporting Unicode conversions at the end of 2013 and is
now in “controlled availability,” but with SAP approval you can use it
now
Speed is not important in the first sandbox migration. The
creation of a repeatable process is far more important.

If you are working with a
BW system that is not
heavily used, or one that has lots of processing
capacity, you can minimize the downtime by
using a “shadow system” during the upgrade
If you use a shadow system (option 2/3), the
system will be copied (not the data) and many of
the upgrade tasks will happen on this “shadow’
system” while the real system is still running
Only in the later stages is the system unavailable
to the users while the configuration and data are
moved to SAP HANA
• This minimizes the downtime of the system

It is now time to check inside SAP HANA Studio that the BW schema has
been created by DMO. You find this under “users” in the HANA navigator.
•
We also have to decide what
support packages we want to
include in the upgrade. Normally
we pick the latest and ignore the
equivalent SPs.

After Migration — The Delta Merge Monitor
•
The Delta Merge Monitor can
help developers and
administrators in load
optimization and processing of
queries in HANA
•
Since the tool can be very
resource intensive, it is
recommended to be used when
the system has minimal usage
(i.e., weekends and nights)
To use the tool, you will have to be on HANA 1.0 Service Pack 5 and BW version 7.3
Service Pack 6 or higher. More details are available in SAP Note 1663501.
68
After Migration — Optimize Database with
Secondary Indexes
•
Normally SAP BW with HANA doesn’t use
secondary indexes. But this can be added
for improving lookup performance in cases
such as transformations.
•
It is important to be aware that secondary indexes, if used extensively,
can require more memory and can also slow down data loads.
Therefore, you may consider adding “HANA hints” in the ABAP code
first (see SAP Note 1662726) or deleting the filter in the SQL statement
and instead executing it in the ABAP engine after HANA returned nonfiltered data (see SAP Note 1740373)
While HANA is much faster than a traditional database, it also can be performance
tuned even faster (this is not normally required as part of typical HANA migration)
69
After the Migration — Table Consistency Checks
• Once
migrated to HANA, you can
check your tables, indexes, and
partition distribution and setup
to assure optimal operations
• This
tool requires that your BW
on HANA system is at least a BW
7.3 Service Pack 6
• You
can access it by running
RSDU_TABLE_CONSISTENCY
To get more information on this tool, check SAP Note 1695778
70
Automated Updates and More Information
• The
BW Migration
cokpit also
provides
information on
new updates,
documentation
and also
additional
information links
for SAP HANA.
•
It is a key tool for all
who do a BW to
HANA migration.

7 Key Points to Take Home
•
•
•
•
•
•
•
There are programs to do pre-readiness checks for an ERP and BW
system for migration to HANA
A BW Migration Cockpit and a new DMO tool are now available to
assist in the tasks
While one is more common, there are actually four possible
approaches to the BW on HANA migration project
SAP is providing guidance and support — more than ever — to make
customers successful, and HANA is now very mature
Standalone HANA projects are also becoming very common, even
with companies that also have BW
Most HANA projects can be done in a matter of weeks, only
extremely large systems may require 4-7 months
Experienced resources with hands-on knowledge is in high demand
