easy+ One-time export of data HANA

Number of

Records: Sales Analysis: > 170 Mio. Sales Statistics: > 35 Mio.

What we did in the prototype

• Two colleagues with no to theoretical knowledge of HANA worked on this

• A whole year of derived data and surrounding customizing was dumped and transfered to a HANA

instance in the AWS cloud with an ABAP stack

- All data were previously anonymised

• The currently-in-use reporting programm was copied 1:1 to the ABAP system in the cloud

- Minor adjustments had to be done to the report, but the core business logic was not even touched

• HANA-Views were created to join the raw data with customizing

• Select statements were modified to use the built HANA views

41

Example of used SQL Statement

SELECT abrlfdat bukrs betrnr vbrart zulaufkz verdkz sv_data

Real-time interactive reporting over 36,2 Millionen invoices

• All invoices grouped by booking date with aggregation (sum of amounts)

• Drill-Down with accounting area, contract type, due date,…

• Access with Integrated Data Access (ALV with IDA in NW7.4)

• Fuzzy search for booking date

Key take aways

49

• Fast ramp-up in project team despite

partial knowledge on SAP HANA at

project start

• New opportunities for interactive usage

of reports highly valuable for Line of

Business

• Prototypes from everyday business

accelerate innovation discovery

• Integration of sidecar database in

existing applications still not equivalent

to best practices

• Acceleration factor 2K and high

compression factor exceeded

expectations

COMPIRICUS: Process Challenge

Preparation: Synchronize SAP FAM data to HANA Cloud Platform by SLT

1. User enters Order information into SAP UI5 frontend.

• SAP UI is using simple HTTP Request for the fly checks. The user gets direct feedback.

2. The Order is stored in the HANA Cloud. User triggers the execution.

3. The Order is sent to SAP FAM via a JSON Request to a published HTTP Connection.

• SAP FAM is calling a BAPI and executing the order.

• Tables in SAP FAM are updated.

4. The SAP FAM tables are synchronized automatically with the HANA instance

• The JSON Model pulls the data from the HANA Cloud. If changes occur the displayed data (Pie

and table) are changed.


COMPIRICUS: Data Transfer Challenge

Direct Synchronization with a SAP

on-premise system using SLT

• Master Data Changes – price

change of a single asset (one

table)

• New Orders – change the

quantities with in the portfolio

(five tables)

• Direct creation of orders via a

JSON request to the R3 System


COMPIRICUS: Data Calculation Challenge

Using HANA to check on the fly

• Check against a black list

• Check single values

• Complex recalculation of portfolio

data, with a possible new deal

and changeable settings

• Using XSJS Services and classes

• Combining HANA based data

with synchronized Data


COMPIRICUS: Key takeaways

1. Using simple JSON is an easy way to send Data between UI5, SAP FAM and HANA Cloud

2. Complex Data access scenarios can be created with Server Side Java Script

3. Working with SAP UI5 is very straight forward

• It is possible to have the same JSON Model behind two SAP UI5 Instances

• Using JSON Model is more flexible than XML Model in case of data updates
