    Job Description

What is SAP?

SAP is a leading provider of software for business and data management and processing. It’s also the force behind Advanced Business Application Programming (ABAP), the language used to write programs in SAP. Solutions cover these areas:

  • Business Technology Platform
  • CRM and Customer Experience
  • Digital Supply Chain
  • Digital Transformation
  • ERP and Finance
  • Experience Management
  • HR and People Engagement
  • Industry Solutions
  • Network and Spend Management
  • Small and Midsize Enterprises

One major purpose of SAP is to centralize core business functions for a business, as well as generate and store data.

What does an SAP developer do?

An SAP developer governs SAP technology and systems by building new solutions, customizing existing ones, and generally overseeing practices related to the software. They use ABAP to work with SAP systems, sometimes focusing on particular products or types of products. Additionally, they work in collaboration with a team to conceptualize new solutions and gather and research requirements. 

The goal of the SAP developer is to help businesses improve the efficiency and practices within the organization and create viable solutions, expanding the organization’s market reach.

How common are SAP developers?

SAP developers are in high demand. Businesses in a wide range of sectors use the technology, so it’s no surprise that so many are seeking experienced professionals who specialize in working with the software.

Zippia reports that there are approximately 5,702 SAP/ABAP developers currently employed in the United States.

1. What is ABAP?

ABAP is an acronym for Advanced Business Application Programming. It’s the programming language used within the SAP R3 program. Using this simple language, developers can customize and improve the software and workflows across a variety of SAP platforms.

ABAP is easy to learn, as long as you already have programming skills and knowledge.

2. What are data classes in SAP?

A data class determines the space that is designated for a database table to be stored on a database server. The classes are defined according to the following parameters:

  • Master data: A type of data that changes very rarely
  • Organization data: Customized data that rarely changes and is input into the system when the system is configured
  • Transaction data: Data that is changed very frequently
  • System data: Data that is used by the R/3 system

3. What are objects in the data dictionary?

The SAP ABAP data dictionary is a centralized data source that defines the structure of objects. Objects within the data dictionary include:

  • Data element
  • Domain
  • Look objects
  • Search helps or match code objects
  • Structure
  • Tables
  • Table types
  • Type groups
  • Views

4. What is a foreign key relationship?

Foreign keys are used to ensure that the data is consistent in tables. They establish a relationship between 2 tables in the ABAP dictionary. This relationship must be clearly stated and defined at the field level. Essentially, the foreign key links tables. Each entry must be carefully reviewed to make sure the data input into the tables doesn’t contradict other data.

5. Describe the 3-tier architecture of SAP.

SAP R/3 is divided into 3 tiers of layers. They include:

  • The presentation layer: This layer, also known as the client layer, has an input device and involves user interaction. It controls the main system and displays via a browser or mobile interface. It can provide a graphical user interface (GUI).
  • The database layer: This layer contains the data within SAP systems and is stored on a separate server. It communicates with the application server.
  • The application layer: The application layer’s purpose is to facilitate communication between the other layers.
Leveraging SAP ABAP, the SAP developer will build programs for SAP software.
