What is SAP BODS?

SAP Business Object Data Services or SAP BODS as it is better known, is an SAP ETL tool that can extract data from different sources, cleanse and transform the data as per requirements, and then move the data to the target destination which could be an SAP application, data mart, data warehouse, flat file, or any operational database. SAP BODS can move and process data in real-time or in batches. It is an all-in-one versatile tool that can process data at enterprise-scale and take care of multiple functions like data integration, data quality, data profiling, and data processing. SAP BODS has a graphical user interface (GUI) to help developers build and implement complex data integration workflows easily without coding. SAP BODS is also known as SAP Data Services or even SAP BO Data Services. How to Carry Out a Successful SAP Cloud Migration

Please Note: SAP OSS Note 3255746 has notified SAP customers that use of SAP RFCs for extraction of ABAP data from sources external to SAP (On premise and Cloud) is banned for customers and third-party tools. Learn More

A short history of SAP BODS

The first stage in the evolution of SAP BODS were two ETL software created by Acta Technology Inc. called Data Integration (DI) tool and the Data Management or Data Quality (DQ) tool. These were renamed later as Business Objects Data Integration (BODI) tool and Business Objects Data Quality (BODQ) tool when Acta Inc. was acquired in 2002 by Business Objects, a French company. Later the Business Objects company was acquired by SAP in 2007 and the two products were merged to form a single product called SAP Business Objects Data Services (BODS).

SAP BODS Architecture and Components

SAP BODS connects to a wide range of data sources and target systems, including databases, files, web services, SAP systems, and more. It has pre-built connectors and adapters to allow for data extraction and loading from different systems. The SAP BODS architecture delivers a reliable, scalable, and secure platform to integrate and transform multi-source data to provide useful, actionable insights. This is an overview of the SAP BODS architecture, its components and how they interact with each other. Create a CDS View in SAP HANA

Management Console

The SAP Data Services Management Console is a web-based application where users can execute jobs, schedule jobs, get auto technical documentation and some reports etc. It has features such as Impact and Linear Analysis, Auto Documentation, Operational Dashboard, Administration, Data Validation and Data Quality Data Reports. The Administrator section is the most used and handles job monitoring, execution, and scheduling. Every environment (e.g. DEV, QA, Production) has its own management console.

Data Services Designer

The Data Services Designer tool has a user-friendly GUI to enable you to outline transformations, data mapping and control business logic. It can help manage repository metadata and enables building of applications comprising of data and workflows. 5 Ways to extract data from SAP S4 HANA

Job Server

The SAP Data Services Job Server uses multi-threading, query optimization, parallel processing, in-memory caching, and in-memory data transformations to deliver data with high throughput and scalability. The Job Server has engines, and enables integration of data from different sources, helps in data transformation and manages data extractions and transactions from ERP applications and other sources. The Data Integration Job Server tool allows movement of data in real-time or in batches. The Job Server tool can also be executed from the Designer console and will retrieve the job information for you from the relevant BODS SAP storage repository and execute the job on the engines. A repository can be linked to more than one engine depending on the number of jobs being run and the need for performance. SAP Extraction using ODP and SAP OData Services (2 Easy Methods)

Engines

After the BODS jobs are run, the Job Server starts up the engines for data processing. The engines of the Job Server use in-memory data transformation and parallel processing to deliver quality, high connectivity, and scalability in processing. The engines are of 3 types:

  • Data Integration Engine
    This BODS engine handles the basic ETL process including data extraction, transformation and loading of data as per defined workflows. It reads and extracts data at source, applies transformations, and loads data to the destination. The SAP Cloud Connector and Why It’s So Amazing
  • Data Quality Engine
    The Data Quality Engine is responsible for data cleansing, data profiling and data enrichment. It offers functionality for data validation, detection of duplicates, address cleansing and standardization of data. SAP ECC and Data Extraction from an LO Data Source
  • Text Data Processing Engine
    The Text Data Processing Engine carries out text data processing for text extraction, text categorization and sentiment analysis. It allows unstructured text data to be integrated into data integration workflows. SAP HANA to Snowflake (2 Easy Ways)

Access Server

Access Server is like the Job Server but differs in the sense that it is used for real-time jobs. It provides a real time XML request-reply message that gathers the message request and delivers it to a real-time service to provide a message reply in a particular period. The Access Server reads the query and sends it to the next available real-time service, passing it through multiple computing resources. Using SAP SLT Transformation Rule in HANA

Address Server

Address Server helps in validating and correcting address data in the data that is being processed. The Address Server must be started before data flows containing Global Address Cleanse or Global Suggestion List Transform are run with EMEA engine enabled.

Repository

The repository is a database that stores user-defined and predefined system objects, such as source and target metadata and transformation rules. This helps in creating repositories on open client / server platforms and for sharing metadata with other enterprise software. There are two types of repositories -Local which is used by the Designer and Job Server, and Central which is used for object sharing and version control. Every local repository is connected to a single or multiple job servers which are executing your job. How to create an SAP OData Service for SAP Data Extraction on SAP BW

Objects

If you have wondered what the Objects in BODS are, it refers to all the entities used in the Data Services Designer. Everything used in the BODS Designer is an Object ranging from projects, jobs, system functions and metadata. They are stored in the local object library and are hierarchical in pattern. Every Object will have properties that define it, including Name, Date Created etc. They also have Options that control how the object is operated. SAP Extraction using ODP and SAP OData Services

Objects are of 2 types- Reusable and Single Use

Reusable Objects in SAP BODS

A Reusable Object can be used multiple times once it is defined and saved in the local repository. This can be done by creating Calls to the definition. The Object Library contains object definitions and when you drag and drop an object from the library, a fresh reference is created for the object. Only one definition exists for each reusable object and if you change that definition, the definition will be changed at all the places where the object is included. RISE with SAP (Everything You Need to Know)

Single Use Objects in SAP BODS

The objects that are created specifically for a job or data flow are single use e.g. a particular transformation created for a data ETL process. Automating the ETL Pipeline

Here are some objects used in SAP BODS

Project

The Project is an object with the topmost level in the hierarchy of the Designer screen. Projects enable you to manage the other objects you create. Only one project can be opened at a time in the window. The SAP Cloud Connector and Why It’s So Amazing

Job

A Job refers to the smallest piece of work that you can schedule and execute independently. Reliable SAP CDC and Data Provisioning in SAP

Script

This refers to part of the code or subset of lines in the procedure. It can execute functions and give values to variables which can be distributed to other steps in the flow.

Workflows

A Workflow comprises of several data flows that make up the flow of work for a complete job. Workflow is a procedure that is optional. These are some of the tasks a workflow does:

  • Calling data flows.
  • Calling a different workflow.
  • Defining the sequence of steps in which a job should be executed.
  • Passing dataflow parameters to and fro.
  • Specifying how errors must be handled during execution.
  • Defining conditions for executing different project parts.

Data Flow

The process by which data from source is transformed into data on the target is a Data Flow. It is a Reusable Object and always called from a Job or a Workflow. It enables you to:

  • Identify the source data you need to query.
  • Define the data transformations to be carried out.
  • Identify the table on target where you need to load the data.

Other commonly encountered terms in the SAP BODS environment

Datastore

A Datastore is an interface or connection that links the source database or application and SAP Data Services. It also enables the import of metadata regarding the data source. These are some of the databases and applications supported by SAP Data Services. It supports:

  • Databases: ODBC, Oracle, DB2, MySQL, Microsoft SQL Server, HP Neoview, Informix, Sybase ASE, Sybase IQ, SAP HANA, Netezza, Data Federator, Teradata. SAP HANA to Snowflake (2 Easy Ways)
