https://blogs.sap.com/2020/09/04/cds-view-entities-the-new-cds-views/


ABAP SQL – ABAP Platform 2020 feature scope (1)

NEW BUILT-IN AGGREGATE FUNCTIONS

ALLOW_PRECISION_LOSS in combination with aggregate function SUM to improve the

performance at the cost of accuracy of the result

Aggregate functions MEDIAN (statistical median), STDDEV (standard deviation), VAR(variance), CORR (Pearson product momentum correlation coefficient), and

CORR_SPEARMAN (Spearman's rank correlation coefficient)

NEW BUILT-IN CONVERSION FUNCTIONS

CURRENCY_CONVERSION - for converting between currencies

TIMESTAMPL, DATS and TIMS – to convert time stamps into dates or times, and vice versa

TO_CLOB and TO_BLOB, and geometry conversion function AS_GEO_JSON to support

streaming and locators on SQL expressions

NEW STRING FUNCTIONS

REPLACE_REGEXPR, LIKE_REGEXPR, and OCCURRENCES_REGEXPR - supporting regular

expressions



DATE AND TIME FUNCTIONS

UTCL_CURRENT, UTCL_ADD_SECONDS, and UTCL_SECONDS_BETWEEN – to perform

operations on time stamps

DATN_DAYS_BETWEEN, DATN_ADD_DAYS, and DATN_ADD_MONTHS – working with arguments

of the built-in data types DATN and DATS

NEW WINDOW FUNCTIONS

FIRST_VALUE and LAST_VALUE in window expressions – to return the first and the last

value of a sorted set of values

NTILE in window expressions – to divide the rows of a window into n buckets with the

goal of filling all buckets with the same number of rows

ENHANCED HIERARCHY FUNCTION

New addition LOAD BULK | INCREMENTAL | load_option – to specify the load policy for a

generated hierarchy

ENHANCED SQL CONDITIONS

SQL functions and cast expressions now supported as operands on the right side of

comparison operators

The operator IN can now be used with a subquery that returns value tuples



VARIOUS OTHER ENHANCEMENTS AND IMPROVEMENTS

Enhanced SELECT, INTO target statement – Inline declaration of host variables allowed

for dynamic FROM-clauses with statically specified SELECT list

NULLS FIRST and NULLS LAST after the ORDER BY clause - determine whether null

values are placed before or after non-null values

Specification of set indicators after the UPDATE FROM-clause - indicate columns for update

STRING and RAWSTRING - allowed for elementary SQL expressions

TYPED LITERALS IN READ POSITIONS

Typed literals for many ABAP Dictionary data types can be used in read positions of

statements where host variables are possible and where it is always treated as an

elementary SQL expression of the specified data type

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 app server

Supportability tools integrated into SAPC, 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)

Supportability and security for ABAP Channels

TCP log

SMWS


ABAP Daemons

Always available ABAP sessions to handle real-time events

Implement a daemon application

Monitor active daemons with SMDAEMON

FEATURES

Daemon session with event handling capabilities

Similar to Windows Services or Linux cron jobs

Long-lived: once started, there is no limit for the lifetime

Robust against errors (E/A/X messages)

Event-driven programming model (ABAP Channels like)

Monitoring & Supportability

USAGE EXAMPLES

Events scheduling

Tracing & Logging

Health Check, clean up of resources, synchronization

of caches and error handling

Proxy-Session for external communication

Check out ABAP Daemons

https://blogs.sap.com/2018/10/18/abap-daemons-always-available-abap-sessions-to-handle-events/


WebSocket RFC

RFC IS READY FOR INTERNET USE

WebSocket RFC uses standard HTTP infrastructure: Reverse

proxies, HTTP routers, etc. instead of proprietary SAP router

VPN tunneling no longer needed for RFC connections across

business networks

Same CALL FUNCTION statement for RFC over WebSocket and

CPIC

Use new destination type “W” for RFC calls via WebSocket

Security: HTTPS enforced and UCON protection for WebSocket

RFC with dedicated allowlist to make Function Modules

accessible from the internet.

Limitations by WebSocket RFC: RFC callbacks

and calling function modules that open SAP GUI-based user

interfaces not supported

Based on ABAP Push Channel technology

Connection types: WebSocket and TCP Socket

Event-driven programming model (ABAP Channels like)

APC Security and Supportability

SYSTEM-INTERNAL RFC FUNCTION MODULES

Develop RFC function modules for purely system-internal use

AMQP-based message exchange via a broker

System-internal RFC function module

SAP HANA

Use SAP Cloud Platform, ABAP

environment, to extend

SAP S/4HANA Cloud or other cloud

solutions from SAP.

Cloud solutions from SAP such as SAP

S/4HANA Cloud provide in-app extensibility to

extend SAP applications and processes. But

there is no support for classic custom ABAP

development on top of SAP S/4HANA Cloud.

SAP Cloud Platform is the foundation to

develop and run custom cloud extensions. The

ABAP environment shall be used for ABAP-

based cloud extensions.

Extension scenario 3: Hub-like usage Decouple ABAP implementations from your core business systems

External user group

Make your cloud app available to a broader audience that does

not have access to your core business systems (e.g. consumer

apps)

Integration hub

Integrate in your cloud extension multiple cloud/on-premise

systems with SAP/non-SAP cloud services

Data integration

Collect data from multiple sources in your cloud extension for

further processing and analysis

Decoupled extension

Cloud extensions use only well defined (remote) APIs of the

Business system. This reduces the risk and effort for business

system upgrades.
