Start with core ABAP fundamentals — data dictionary, internal tables, modularization, and classical reports — because projects and interviews still expect them. Then move to HANA-specific skills: modern ABAP syntax, code pushdown, CDS views, AMDP, and performance optimization, followed by OO-ABAP and ALV. Finish with OData and Fiori/UI5 basics so you can handle end-to-end development. Above all, practice on a live system by building small RICEFW objects — hands-on work is what turns tutorials into job-ready skills.

SAP ABAP on HANA is modern ABAP development for systems running on the SAP HANA in-memory database, mainly S/4HANA. Instead of pulling large volumes of data to the application server, heavy processing is pushed down to the HANA database where it runs much faster. It uses enhanced Open SQL, CDS views, AMDP, and performance-optimized coding, and it feeds OData services and Fiori apps — which is why ABAP on HANA developers often work as full stack developers.

A practical sequence is: modern ABAP syntax (inline declarations, constructor operators, string templates), enhanced Open SQL, CDS views, AMDP, performance tuning and code pushdown, OO-ABAP, and object-oriented ALV. After that, add OData services and Fiori/UI5 basics, since most S/4HANA projects now expect ABAP developers to deliver both the backend logic and the services behind Fiori apps.

A certification helps your profile clear initial screening at large consultancies and is useful for freshers without project experience. However, most Indian companies hiring for ABAP on HANA roles test practical skills — CDS views, performance tuning, OO-ABAP, and real RICEFW scenarios — in technical rounds. So treat certification as a supporting document rather than a job guarantee; documented hands-on practice and project work usually carry more weight.

Download the latest Eclipse IDE, then install ABAP Development Tools (ADT) through the Eclipse update site using Help > Install New Software. After restarting, open the ABAP perspective, create a new ABAP project, and connect it to your S/4HANA system using the system URL and your logon credentials. ADT is essential for ABAP on HANA work because CDS views, AMDP, and many new features are properly supported in Eclipse, not in the classic SAP GUI editor.

ABAP needs a live SAP system — it cannot be practiced fully on a laptop like Python or Java. Learners usually choose between the SAP BTP free tier (ABAP environment), community or rented S/4HANA access, or a shared SAP practice server run by mentors and training groups at a fraction of personal licensing cost. Whichever route you pick, confirm you can create CDS views, write and debug reports, and expose and test OData services, because these cover most interview and project scenarios.

Interviewers typically cover code pushdown and why it matters, CDS views (including annotations and when to use them over classic views), AMDP, new ABAP syntax, performance optimization such as avoiding database access inside loops, OO-ABAP concepts, and enhancement techniques. For experienced roles, expect scenario-based questions on optimizing slow reports, designing CDS views for Fiori apps, and explaining real RICEFW objects you have built.

Fresher rounds usually focus on fundamentals: types of internal tables (standard, sorted, hashed), classical vs interactive reports, data dictionary objects, modularization, BAPI, BADI, and user exits, plus simple coding tasks on joins or control-break statements. Interviewers also expect you to explain one mini project end to end, so prepare a clear story around anything you built during training.

Expect questions like what a CDS view is and how it differs from a DDIC view, what annotations are and which ones are used for OData/Fiori exposure, associations vs joins, parameters in CDS views, extension views for standard objects, access control, and how CDS views feed Fiori applications through service bindings. Being able to explain the building blocks — DDL source, fields, associations, and annotations — is often enough to stand out at fresher level.

Keep it one to two pages, single column, and ATS-friendly with standard section headings. List technical skills in a clean block (ABAP, CDS views, OO-ABAP, ALV, OData, Fiori/UI5 basics, performance tuning) and describe projects with bullets that show the business problem, what you built, and the result. Mirror keywords from the actual job description so automated screeners score you well, and avoid generic objectives or skill lists copied without project proof.

SAP Fiori is the modern user experience layer for SAP systems. It gives business users role-based, app-style screens that work on desktop and mobile instead of dense SAP GUI transactions. Under the hood, Fiori apps are built with SAPUI5 and fetch data through OData services from the backend — which is exactly where ABAP developers fit in, creating and optimizing the services and CDS views that power those apps.

The SAP Fiori Launchpad is the role-based home page that hosts all the Fiori apps a user is entitled to. It displays apps as tiles organized into catalogues and groups, supports personalization, search, and notifications, and is assigned to users through backend roles. For developers, it is the central place where the apps you build actually appear for end users.

In most companies you open it in a browser through a link that ends in /sap/bc/ui2/flp and log in with your SAP user — the roles assigned to you decide which tiles appear. In embedded on-premise deployments you can also launch it with the SAP Fiori tcode /UI2/FLP from the SAP GUI. If your apps or tiles are missing, the cause is usually role or catalogue assignment rather than the launchpad itself.

The SAP Fiori apps reference library is SAP's official catalogue of every standard Fiori app. For each app it lists the business role it supports, required SAP releases (S/4HANA on-premise and cloud versions), configuration steps, app ID, and technical dependencies. Functional consultants use it to check app availability, while developers use it to find implementation information and backend requirements before an app can run.

For campus placements, cover Python basics (data types, loops, functions, OOP), then the standard patterns asked in coding rounds: strings, lists, dictionaries, recursion, and easy-to-medium DSA problems. Practice writing clean code without an IDE, revise commonly asked programs, and add one or two small projects to talk about in interviews. Most service-based companies test logic over advanced frameworks, so depth in fundamentals matters more than knowing many libraries.
