I
learned a term "ABAP strict" for first time in autumn 2021 during an openSAP course called Introduction to ABAP in the Cloud.
So what is "ABAP strict" sometimes called as "ABAP strict
mode"?
The
ABAP strict is ABAP programming language version that uses only a subset of the
Classic ABAP's syntax. If we think about ABAP in this context, there are now
two versions of ABAP.
The
first version is ABAP classic. It is
the one that we all (hardcore SAP stack programmers) know from on-premise SAP
solutions world like R/3, ERP, ECC including SAP S/4HANA on-premise as well.
Another
version is ABAP strict. It is the
one used in cloud based SAP solutions like SAP S/4HANA Cloud, ABAP environment
as well in SAP
Business Technology Platform (BTP) ABAP environment.
What
are the differences between the two ABAP versions?
As
both the versions are used in different environments (on-prem vs cloud), it naturally
drives the language’s feature sets.
In
case of ABAP strict access to repository objects is given only by released APIs. This means you cannot
directly manipulate e.g. database tables with CRUD SQL statement. Instead there
a whitelist of allowed APIs to do that. Allowed APIs are checked statically at
compile time, as well as runtime.
Moreover,
only ABAP
Development Tools (ADT), based on Eclipse IDE platform, can be used as development
tool. Remember it is about the cloud - SAP GUI is no more the ABAP developer
IDE.
In
addition, ABAP language keyword set is restricted if compared to ABAP classic. There
are many ABAP commands that are obsolete in the cloud environment. E.g. access
to SAP server OS, screen manipulation (no GUI, FIORI is the UI), no SQL for data
in database tables manipulation, no more WRITE command, dynamic connections,
client overrides, relative keywords are not supported, secondary database
connection is not allowed etc. just to name a few. Naturally, there is a stricter
syntax rules and checks are applied to all elements, including ABAP classes and SQL statements.

Hi,
Can you confirm that with strict ABAP,we have to use only class to practice ABAP and do you think NW is died?
Thanks
Hello,
1/ yes in ABAP could (~ ABAP strict) an ABAP RESTful Programming Model needs to be followed. That means there is no report/program any more. ABAP code is represented in ABAP class and other code artefact that are allowed in cloud environment.
2/ whether NW is death? We see that NW is sunsetting 9see more details here" Life after life of SAP NetWeaver and Business Suite/ECC. However technologies like ABAP in cloud will remain. Just we need to align with a new terminology. In this case it is ABAP Platform.
cheers
