What Are Tier-1 ABAP Cloud Objects in SAP ABAP?

SAP is changing the way how the developers write ABAP code. Well, if you are planning to learn SAP ABAP, then you need to notice certain inventions that have taken place recently. Well, these are the new concepts that every ABAP developer needs to understand. One of the most important concepts is Tier-1 ABAP Cloud objects.

This can be learn easily by taking the SAP ABAP Online Training, where you will learn the unique ways to build applications and how this matters for your career. This online training can be the best way to learn everything from scratch for beginners. So let’s begin discussing the meaning of ABAP Cloud.

What Is ABAP Cloud?

First, let’s understand ABAP Cloud. It’s SAP’s new way of developing applications that work in the cloud. The old way of writing ABAP code doesn’t always work well in cloud systems. So SAP created new rules and new types of objects.

SAP divided all ABAP objects into different tiers. Tier-1 objects are the best ones, as they follow all the cloud rules and will keep working when SAP updates its systems.

When you join SAP ABAP Training, you’ll learn that Tier-1 objects are now the standard for all new development work.

Why Did SAP Create Tier-1 Objects?

The old way of writing ABAP had some problems:

• Developers could change SAP’s core code, which caused issues during updates
• The code broke when SAP released new versions
• Different developers wrote code in completely different ways
• Moving to the cloud was difficult

Tier-1 objects solve these problems. They make sure your code is clean, stable, and works in cloud environments.

Rules for Tier-1 Objects

For an object to be Tier-1, it must follow strict rules:

• Only Use Released APIs:

You can only use code and functions that SAP officially supports. No accessing internal SAP stuff that might change.

• No Direct Database Access:

You cannot write SELECT statements directly on database tables. You must use proper views instead.

• Work in the Cloud:

Your code must work in cloud systems where you don’t have full control, like in old on-premise systems.

• Follow Standards:

Everything must be properly structured and documented.

Any good SAP ABAP Certification course will teach you these rules because they’re important for passing exams and doing real work.

Main Types of Tier-1 Objects

1. CDS Views

CDS stands for Core Data Services. These are the new ways to read data from the database.

What They Replace:

Old database views and direct SELECT statements on tables.

What They Do:

They give you a clean, safe way to access data. You define what data you need and how it should look.

Why They’re Better:

• They include security checks automatically
• They can do calculations for you
• They link related data together easily
• They work the same way everywhere

When you take Training, you’ll spend a lot of time on CDS views. They’re used everywhere in modern SAP systems.

2. RAP Business Objects

RAP means RESTful ABAP Programming. These objects handle all your business logic.

What They Include:

• Rules for what users can do with data
• Code that runs those rules
• Ways to expose your data to other applications

Real Example:

Let’s say you’re building an app to manage employee leave requests. Your RAP business object would:

• Allow the employees to create the leave requests.
• To check if they have enough leave balance.
• Send notifications to managers
• With time, update the leave balance whenever approved.
• Preventing employees from deleting the approved requests.

This is the main part of SAP ABAP Training in Gurgaon and other professional courses where such important things are taught.

3. Service Definitions and Bindings

These objects expose your data and logic so other applications can use them.

Service Definition:

You list what data and operations you want to share.

Service Binding:

You choose how to share it,  through web services, mobile apps, or other ways.

Why This Matters:

Modern applications need to talk to each other. Your ABAP code might need to send data to a mobile app or receive data from a website. Service definitions and bindings make this possible.

4. Metadata Extensions

These add display information to your CDS views without changing the views themselves.

What They Control:

• How fields are labeled on the screen
• Which fields show up and in what order
• How data is grouped
• What help is available for each field

Why This Is Smart:

You can have the same data appear differently across apps. One view for reporting, another for data entry, without duplicating your data logic.

Conclusion:

Tier-1 ABAP Cloud Objects are no longer optional, as they are the standard way to develop SAP systems. So if you are just beginning fresh or have years of ABAP experience, then you need to learn these objects. Well, the shift to cloud development is happening fast. Developers who get ahead of this curve will have the best career opportunities.
