What is SAP ABAP?

ABAP is a SAP-specific advanced programming language introduced in the 1980s. The first versions were mostly focused on the SAP R/2 mainframe platform, supporting the framework. Later in 2000, it was updated with object-oriented features and since then it has also been used for web technologies, real-time data processing and advanced analytics.

Now, it allows developers to create custom reports, improvements and applications for SAP systems. It can build both analytical and transactional applications that enable businesses to manage their data, operations and processes effectively.

Setting Up the ABAP Development Environment

Once you have the basic understanding, you can set up the ABAP development environment. This setup requires a Cloud Foundry subaccount to run. You can create the account from the SAP Discovery Center Service Plan. The complete setup involves the following steps:

Step 1: Create a Sub Account

• Log in to your Global account.

• Now click on the Create option and then Subaccount from Account Explorer as shown below.

• A window asking for some information will pop up on your screen.

• Fill in the information and click on the Create button.

STEP 2: Enable Cloud Foundry

• Log in to your sub account as administrator.

• You will see a Cloud Foundry Environment, click on it and choose the Enable Cloud Foundry option.

• Click on the Create button without changing the preconfigured entries.

Step 3: Create a Space

• Click on the Create Space button.

• Now provide a name to the Space.

• Click on the Create button without changing the space roles.

Step 4: Increase a Quote for the ABAP Environment

In case you are a working professional and have an enterprise account, create a quote for the services you will use. These services then will be available in the Service Marketplace of the sub account to subscribe.

• Go to the Global account.

• Then click on the Entitlements and then Entity Assignments button.

• Choose a subaccount for ABAP and click on the Select button.

• Click on the Choose Configure Entitlements, Add Service Plans and then Add 3 Service Plans button.

• Click on the Save button.

Step 5: Increase a Quote for ABAP Web Access

Follow the same process of Step 4 and choose the Add 1 Service Plan button from Web access for ABAP section.

Step 6: Create an ABAP System

• Log in to the SAP BTP cockpit and go to the Cloud Foundry sub account.

• Navigate and go to the Services Service Marketplace, and you will see a list of different services available.

• Select an ABAP environment, click on Create and you will see a wizard as shown below.

• Choose the standard service plan, Cloud Foundry as the run-time environment, use a space name and click on the Next button.

• Now provide additional instance parameters or use the default ones. Ensure you do not use compute units more than your sub account has.

• Click on the Next and then Create button.

• Click on the View Instance button.

• Choose the Instances and Subscriptions option to see the progress.

• Once the process is complete, select the intense name from default_abap.

• This will show an error message as you do not have the subscription.

Step 7: Subscribe Web Access for ABAP

The ABAP administrator launchpad can not be accessed without a subscription. It requires at least one subscription per sub account.

• Log in to the SAP BTP cockpit again.

• Go to Services and select the Service Marketplace button.

• Select the subscription for SaaS application tile Web access.

• Click on the Create button.

• Wait until the subscription is provisioned from the Instances and Subscriptions section. Once done, click on it and you will see a success message.

• Now you can use the ABAP administrator launchpad in your ABAP environment.

SAP ABAP Tutorial: Core Concepts Explained

This section introduces the core concepts of advanced business application programming language. It will give you a basic familiarity of how this programming language is used in developing enterprise applications.

1. Architecture

It is a client-server model also known as R/3 architecture. It consists of three layers including presentation, application and database.

A. Presentation Layer

This layer provides two mechanisms named Input and Output. The input mechanism lets individuals communicate with the system. The output mechanism lets the system see the results of human engagement. It also includes SAP GUI, a graphical user interface. The SAP GUI is installed on individual machines.

B. Application Layer

The application Layer is the central processing hub where business logic and transaction processing occur. It receives requests from the presentation layer, interacts with the database layer for data retrieval and storage and manages the overall flow of user interactions. This layer is built upon the ABAP Application Server (AS ABAP), which provides the runtime and development environment for ABAP programs.

C. Database Layer

The database Layer is the foundational layer responsible for storing and managing all data related to the SAP system. This data includes master data, transaction data, configuration settings and user information. It is the last player that forms the core of the three-tier architecture.

2. Repository

A repository is a central system of SAP that stores and manages ABAP development objects. These objects can be of many types, including programs, function modules, structures and other custom objects. It is just like a database for the development environment that enables developers to create, modify and track their code.

A repository is also referred to as the key component of the ABAP development lifecycle. It facilitates collaboration and version control through the Change and Transport System (CTS). It provides a structured and effective way to store data in tables and fields.

3. Data Types

ABAP supports various data types, including numeric, character, date, time, and more. This programming language also lets developers define global data types with the help of the ABAP Dictionary. Another option is to use the TYPE addition of ABAP statements that refer to these data types. Using the Dictionary tool is the traditional way to define a data type in the ABAP Workbench.

4. Object-Oriented Programming

Object-oriented programming is one of the robust features of the ABAP programming language. It comes as an extension called object-oriented ABAP (OO ABAP). This extension allows developers to build code using object-oriented principles. With this principle, their code and data are organized into objects in a way that code can easily operate on data. This provides better reusability, modularity and maintainability. It is preferred to use OO ABAP over conventional methods.

5. Control Structures

Control structures are mechanisms that manage the flow of execution within a program. They allow developers to divide a program's processing block into smaller, manageable sections. This enables conditional execution, repetition and more complex program logic. ABAP provides various control structures for program logic, including:

A. IF-THEN-ELSE

It is the most common conditional branching statement that involves a pair of keywords, including IF and ENDIF. It implies a condition where the block will only execute if the condition after IF is satisfied.

B. CASE

It is a control structure that provides a way to select and execute different code blocks based on the value of a variable or expression. It offers an efficient alternative to nested IF statements.

C. FOR

It is another control structure used to iterate over data structures like tables. They allow developers to process each element of a table or other structures sequentially.

D. WHILE

It is the fundamental control structure of SAP ABAP. It is used for iterating a part of code where the given condition remains satisfied.

E. DO & ENDDO

The DO control structure is used to create unconditional loops. This means that the block of code within the DO and ENDDO statements will execute repeatedly until an explicit exit condition is met within the loop.

ABAP Best Practices to Consider

It is important to consider using the ABAP best practices when writing code in ABAP. Here are some of the most important best practices one should follow:

• Use of clear and descriptive names for methods, variables and classes, as the name should convey the intent and purpose of the code.

• Try to build small and concise methods that focus on a particular task. This way the code will be easier to understand, test and maintain.

• Avoid using hard-coded values as much as possible, as they are hard to maintain. You can also use constants or configuration tables instead of them. The best part of this practice is to implement changes without modifying the code.

• Only add comments to explain why a block of code exists, not its working. An ideal code should not rely on comments for explanation.

• Keep your coding style consistent throughout the ABAP programs to improve their readability. This includes spacing, indentation and naming conventions.

• Using subroutines, methods or function modules to break down the complicated processes into smaller components.

• Use TRY-CATCH blocks to implement proper error handling. This ensures that the code gracefully manages exceptions and provides accurate error messages.

• Use efficient queries and a minimum number of databases. Do not retrieve data until specific conditions like avoiding nested SELECT statements is required.

• Keep yourself updated with the latest syntax and features of SAP ABAP. Inline declarations, expressions, and new string operations are some of the latest features you should know about.

• Validate your code's functionality to ensure it behaves as expected in each case.
