Why code breakouts make sense …

Unleash the full potential of your

SAP HANA database

Some scenarios require

selective measure

Highest performance requirements

e.g. with complex calculations

Use of database / analytical engine

specific functions required

Open SQL and CDS views are not

sufficient to solve problem efficiently

Restrictions

Database specific

SAP HANA only

No automatic fallback for any DB

Enhancement to Logical Database Schemas

Current ABAP database schema can now be mapped in the transaction DB_SCHEMA_MAPwhen flagged appropriately

Various Restrictions Removed

Tabular input parameters now allowed in AMDP implementations of CDS table functions

Tabular input parameters of AMDP implementations can now be set optional

Similar behavior as in regular methods when declaring a replacement parameter with

addition DEFAULT for AMDP implementations

Improved Client Handling

New mandatory option CDS SESSION CLIENT required when accessing CDS database

views of CDS view in AMDP method


AMDP scalar functions support starting with release 7.53

AMDP scalar functions now supported alongside

AMDP database functions

Based on the SAP HANA scalar function

Implemented as an AMDP function in an AMDP class

▪ Elementary data types of input parameters

▪ With an elementary return value

▪ New database-specific option DETERMINISTIC in the ADMP function

implementation to allow automatic result buffering for the duration of a

query

Can be called in ABAP like any regular function method and

used as a functional method in a functional method call

Where to invest now to be prepared for the ABAP Programming Model?

Follow the programming model and best practices and use…

*Core Data Services (CDS) for database artefacts(≥ 7.40, Documentation)

*CDS Metadata Extensions for UI Annotations(≥ 7.51 SP2, Documentation)

*DCL for read/query instance-based authority checks( ≥ 7.50, Documentation)

BOPF stand-alone(≥ 7.40, Documentation, newer releases: CDS/BOPF integration)

*BOPF and CDS integration including draft(≥ 7.51 SP2, Documentation)

Gateway integration of CDS or BOPF

(= 7.40, Documentation, newer releases: OData Exposure)

*OData Exposure of CDS / BOPF for

SAP Fiori and future development(≥ 7.50 SP5, Documentation)

Floorplan-Manager integration of CDS and BOPF(≥ 7.40, Documentation)

Implement things that are already solved

Manual implementation of read-only calls to DB

Business logic mixed with technical aspects (e.g. locks, authority-check, LUW handling, persistency)

Business logic mixed with protocol specific APIs (e.g. PBO/PAI, Gateway classes: DPC_EXT)

YOU SHOULD DO NOT

BENEFITS

Reuse / prepare your skillset and coding for the future

Reuse CDS and DCL in SAP S/4HANA

Lower TCD for the future: Minimal investment on

technical protocol level

Messaging proxy(e.g. MQTT client in Gateway’s SAP

Enterprise/Unified Eventing)


ABAP Daemons (3)


Start-Up Configuration – Bootstrapping of daemons

by application server

Each start-up configuration entry specifies for a

daemon application:

how many many instances of a daemon should be started in

the system and on which application servers

under which user a daemon should be started

A daemon user can be provided as

RFC destination (with logon information)

user name (trust relationship to DDIC user has to be

maintained)

Reuse of existing security concepts of the RFC

SMDAEMON transaction

Start-up configuration


Supportability

Standard ABAP supportability tools for debugging, runtime

analysis and performance, kernel trace

Transaction SMWS shows active WebSocket, TCP Socket

and MQTT subscriptions on each application server

Supportability tools integrated into SAPC and SMWS

transactions

TCP log

Security

Virus scan profile for messages, authorization for involved

addresses and domains

Secure communication using SSL (TCPS for TCP Sockets

and WSS for WebSockets)
