ABAP Managed Database Procedures (AMDP)
Use strengths of SAP HANA with SQLScript
Parallelization & significant
reduction of transferred data
 Declare data selection via SELECT
or CE (Calculation Engine)
functions
 supports parallel processing
 Multiple results (instead of only
one result set)
 Control logic such as if/else (not
available in SQL)
 Local variables for intermediate
results (instead of globally visible
views)
Access to SAP HANA native
engines and function libraries
 Text Mining, Predictive analysis,
Financials, Geo-spatial, …

ABAP Managed Database Procedures (AMDP)
Simplify developer experience by integration in ABAP infrastructure
AMDP provided by means of methods of
global classes marked with tag interfaces
 AMDP classes and AMDP methods
 Called like any other regular ABAP methods
 Modification-free extension via AMDP BAdIs
Fully integrated in and managed by the ABAP
infrastructure
 Procedure created at first AMDP call
 Detailed analysis of runtime errors in ST22
 Transport analog to regular ABAP classes
SQLScript source code editing in ABAP editor

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

Example of used SQL Statement
SELECT abrlfdat bukrs betrnr vbrart zulaufkz verdkz sv_data

Based on initial experiences, an additional use case was
implemented
48
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
