• Implementation of HANA as a Data Mart (ERP side car) to speed up Vodafone

MEC (Month End Close) process

• Real Time Data Provisioning via SLT (PRD: >30 Tables and 1Bn rows of data)

• Use of the Analysis for Office reporting client, to deliver reports directly in Excel.

• Administration and End User Training for 35 users distributed globally

• “Live” Proof Of Concept – 2 months in June/July 2012

• Implementation into Production – 3 months (much of that time spent testing) with

a Business Go-Live mid-November 2012.

If results of HFM reports are not satisfactory from a reporting point of view, the changes

are done either in ECC (long waiting time 90-150 min before seen them reflected in BI, or in

FDM/HFM directly and then posted back in ECC (this brings the risk of potential point of

misaligned in the systems).

Currently live in production globally with HANA

By generating key financial reports in real time that used to take hours every time

they were run, SAP HANA saved a day out of the seven-business-day process

Helped the company gain labor efficiency benefits over the next 4 years

96% Reduction in data extract, processing, and load times

“Month-end closing is a highly visible and critical application at Vodafone. Speeding it up was

very valuable in its own right, as well as a great first application of SAP HANA to demonstrate

its power to the company.”

Valentina Del Frate, Project Manager, Vodafone Group Plc

“For the first time ever I can post an entry and see its impact on HFM after minutes. Thanks

for everyone contributed in HANA.”

End User, Vodafone.

Project Benefits


34 tables required to be loaded to HANA via SLT and joined together in a

model to produce csv output for HFM (Vodafone’s 3rd party consolidation

tool at present).

To generate the Output file, the user was allowed to choose a Fiscal

Year, a Fiscal Period and one or many HFM Entities. (An HFM Entity was

a group of one or more SAP Company Codes)

There were 20+ COPA tables of the form CE4XXXX_ACCT where XXXX

was a different Operating Concern (DE01, GB01 etc).

The output format for HFM was 20 columns and expected to be only

thousands of rows long, however HANA had to sift through billions of

rows to arrive at that final output list during each user query

Detailed Requirements (1)


The population of the Output was defined differently for different groups

of GL Accounts. (For example GL Accounts with a number starting between 10… and 49… had

one set of rules on how to populate each of the columns of the output file (sometimes some fields were

required to be set to initial values for example) whereas GL Accounts with a number starting between

50… and 69… had another set of rules on how to populate each of the columns of the output file)

An iterative lookup of the Movement Type over prior fiscal years (typically

handled by ERP itself in Application logic above the BSEG Cluster table)

was also required to be modeled

Numerous instances of Bad Data from ECC that had to be covered up

with some creative modeling in HANA

User interaction was required with the final output from HANA as well as

a reconciliation report

Detailed Requirements (2)


BKPF as Attribute View (keeping

BSEG as only table in Analytic

View Data Foundation)

Filters on BSTAT in BKPF

Use of TKA02 as KOKRS not

always reliable from BSEG

HFM Mapping table inclusion

Detailed Modeling Examples – First Steps. Attribute Views.

CSKS static filter for time

dependent data

Calc View as

workaround for

unexpected ECC data


BSEG as only table in Analytic

View Data Foundation

Filters on HKONT for relevant GL

account number ranges

Detailed Modeling Examples – First Steps. Analytic Views.

Intentionally a very

simple Analytic View. No

Calc

Attributes/Measures.

The Final Live POC

Analytic View only for

Spanish Operating

Concern


Detailed Modeling Examples – First Steps. Calculation

Views.

Projection Node above

each of 4 „Vanilla“

Analytic Views for

uniformity and filter

expressions functionality

Filter Expressions

passed down to lowest

level Analytic Views

(confirmed with PIRT

trace)

("GJAHR" ='$$FYEAR$$' and "MONAT" <='$$FPERIOD$$') OR "GJAHR" <'$$FYEAR$$'

"GJAHR" ='$$FYEAR$$' and "MONAT" <='$$FPERIOD$$'


Detailed Modeling Examples – Final Calculation View

Additional complexity of many

Operating Concerns.

Single Calculation View desired

Design is for majority of nodes to

bring back zero values very very

quickly

Deployment of Analytical Views to

Join Engine helped in this case

Other Thoughts: Table partitioning,

CE4 Mega table idea to be

revisited


HANA MEC Phase 2 – Planned

Go Live in March 2013.

A set of 5 BO WebI reports

enabling the business to analyse

financial data before the HFM

submission.

Non-SAP data (complex

mappings) upload in HANA using

BO Data Services.

Complex „on the fly“ mapping

modeled with HANA Calculation

Views.
