What are the 3 layers in SAP Workflow Architecture?
SAP Workflows

SAP R/s system contains pre-determined SAP business workflows that aid in designing business processes. The workflows in the SAP system ensure the channeling of the right tasks in the correct sequence to the right audience. The workflow architecture automates and aids business processes that require human effort.

It is fundamental to business process integration. The SAP business suite facilitates easy monitoring of business transactions and holistic completion of processes. This article contains detailed information about the 3 layers of SAP workflows architecture.

What are SAP Business Workflows?

SAP systems use business workflows to implement business processes. They are essential components in an SAP system that help to design simple releases to complex recurring processes. Workflow engines help users manage business processes with efficiency.

The 3 Layers in SAP Workflow Architecture

SAP workflow architecture comprises three layers: business object, business process, and organization model.

Business Object

A business object denotes the collection of an entity’s procedures, techniques, or events in the business process. The main SAP business objects include materials, customers, and dealers. The Business Object is the lowest level in SAP workflow architecture.

The SAP system uses business objects to provide services in the form of executable procedures. A Business Object Repository models business processes and objects. Business objects reduce the SAP system’s complexity by breaking it down into smaller units. The attributes of business objects include:

• The use of Object Type ID to internally identify the business object.
• Use of the Object Name for external identification of the business object.
• Inheritance of business object components from the Super Type It.
• Each business object bears a descriptive name and a brief description of the business object’s type.
• A component is assigned to each business object.

Business Process

In SAP workflow architecture, business processes are defined in the Workflow Builder. Work processes are referred to as high-availability activities and entail single-step tasks/workflow templates. Business processes occupy the middle level of a workflow architecture. Business processes specify the steps to be taken in the workflow.

Organizational Model

The organization model occupies the top layer of SAP workflow architecture. It defines the people responsible for actions in business workflow. These individuals are also known as the actual agents involved in business workflow.

What is SAP R/3 Architecture?

SAP architecture can be described as a set of principles, patterns, and best practices outlining an organization’s SAP environment architecture. Companies can create secure and reliable platforms to run their processes effectively using SAP architecture. SAP R/3 is a 3-tier architecture that consists of three layers: the presentation layer, the application layer, and the database layer. In SAP R/3, R represents a real-time system.

The Presentation Layer

The presentation layer of the three-tier architecture is composed of the SAP graphical user interface (SAP GUI). SAP GUI provides a graphical user interface where users can enter and display data. This layer of the SAP software architecture is the interface between the SAP R/S3 system and its users. It conveys the user’s input to the application server and displays the data received from the server.

Application Layer

The layer contains one or more application servers and an SAP message server. Each application, server provides a set of services for running the R/3 system. The message server facilitates communication between the application servers in the SAP architecture, passing requests between the servers. It uses application server groups and current load-balancing information to assign the most suitable server to a user whenever he/she logs onto the software system.

Database Layer

The database layer comprises a central database system in which all the data in the R/3 system is stored. The database system contains the database management system (DBMS) and the database. SAP HANA is SAP’s own manufactured database that is compatible with others such as the Oracle database.

These files contain data necessary for customization and control of the R/3 system, as well as application code. The applications are composed of screen definitions, program codes, menus, crystal reports, and function modules that are stored in the R/3 repository.
