Most frequently asked SAP BODS Interview Questions

Q1) What is the use of Business Objects Data Services?

Ans: BusinessObjects Data Services provides a graphical interface that allows you to easily create jobs that extract data from heterogeneous sources, transform that data to meet the business requirements of your organization, and load the data into a single location.

Q2) Define Data Services components?

Ans: Data Services includes the following standard components:

  • Designer
  • Repository
  • Job Server
  • Engines
  • Access Server
  • Adapters
  • Real-time Services
  • Address Server
  • Cleansing Packages, Dictionaries, and Directories
  • Management Console 

Q3) What are the steps included in the Data integration process?


  • Stage data in an operational data store, data warehouse, or data mart.
  • Update staged data in batch or real-time modes.
  • Create a single environment for developing, testing, and deploying the entire data integration platform.
  • Manage a single metadata repository to capture the relationships between different extraction and access methods and provide integrated lineage and impact analysis.

Q4) Define the terms Job, Workflow, and Dataflow?


  • A job is the smallest unit of work that you can schedule independently for execution.
  • A workflow defines the decision-making process for executing data flows.
  • Data flow extract, transform and load data. Everything having to do with data, including reading sources, transforming data, and loading targets occur inside a data flow.

Q5) Arrange these objects in order by their hierarchy: Dataflow, Job, Project, and Workflow?

Ans: Project, Job, Workflow, Dataflow.

Q6) What are reusable objects in DataServices?

Ans: Job, Workflow, Dataflow.

Ans: A transform enables you to control how datasets change in a dataflow.

Q8) What is a Script?

Ans:  A script is a single-use object that is used to call functions and assign values in a workflow.

Q9) What is a real-time Job?

Ans:  Real-time jobs “extract” data from the body of the real-time message received and from any secondary sources used in the job.

Q10) What is an Embedded Dataflow?

Ans: An Embedded Dataflow is a dataflow that is called from inside another dataflow.

Q11) What is the difference between a data store and a database?

Ans: A datastore is a connection to a database.

Q12) How many types of datastores are present in Data services?

Ans: Three types:

  • Database Datastores: provide a simple way to import metadata directly from an RDBMS.
  • Application Datastores: let users easily import metadata from most Enterprise Resource Planning (ERP) systems.
  • Adapter Datastores: can provide access to an application’s data and metadata or just metadata.

Q13) What is the use of the Compact repository?

Ans: Remove redundant and obsolete objects from the repository tables.

Q14) What are Memory Datastores?

Ans: Data Services also allows you to create a database datastore using Memory as the Database type. Memory Datastores are designed to enhance processing performance of data flows executing in real-time jobs.

Q15) What are the file formats?

Ans: A file format is a set of properties describing the structure of a flat-file (ASCII). File formats describe the metadata structure. File format objects can describe files in:

  • Delimited format — Characters such as commas or tabs separate each field.
  • Fixed width format — The column width is specified by the user.
  • SAP ERP and R/3 format.

Q16) Which is NOT a datastore type?

Ans: File Format

Q17) What is the repository? List the types of repositories?

Ans: The DataServices repository is a set of tables that holds user-created and predefined system objects, source and target metadata, and transformation rules. There are 3 types of repositories.

  • A local repository
  • A central repository
  • A profiler repository

Q18) What is the difference between a Repository and a Datastore?

Ans: A Repository is a set of tables that hold system objects, source and target metadata, and transformation rules. A Datastore is an actual connection to a database that holds data.

Q19) What is the difference between a Parameter and a Variable?

Ans:  The parameter is an expression that passes a piece of information to workflow, data flow or custom function when it is called in a job. A Variable is a symbolic placeholder for values.

Q20) When would you use a global variable instead of a local variable?


  • When the variable will need to be used multiple times within a job.
  • When you want to reduce the development time required for passing values between job components.
  • When you need to create a dependency between job level global variable name and job components.

SAP BODS Complex Scenarios

Q21) What is Substitution Parameter?

Ans: The Value that is constant in one environment, but may change when a job is migrated to another environment.

Q22) List some reasons why a job might fail to execute?

Ans: Incorrect syntax, Job Server not running, port numbers for Designer and Job Server not matching.

Q23) List factors you consider when determining whether to run workflows or data flows serially or in parallel?

Ans: Consider the following:

  • Whether or not the flows are independent of each other
  • Whether or not the server can handle the processing requirements of flows running at the same time (in parallel)

Q24) What does a lookup function do? How do the different variations of the lookup function differ?

Ans: All lookup functions return one row for each row in the source. They differ in how they choose which of several matching rows to return. '

Q25) List the three types of input formats accepted by the Address Cleanse transform?

Ans: Discrete, multiline, and hybrid.

Q26) Name the transform that you would use to combine incoming data sets to produce a single output data set with the same schema as the input data sets?

Ans: The Merge transform.

Q27) What are Adapters?

Ans: Adapters are additional Java-based programs that can be installed on the job server to provide connectivity to other systems such as or the JavaMessagingQueue. There is also a software development kit (SDK) to allow customers to create adapters for custom applications.

Ans: Name match standards to illustrate the multiple ways a name can be represented. They are used in the match process to greatly increase match results.

Q38) What are the different strategies you can use to avoid duplicate rows of data when re-loading a job?

Ans: Using the auto-correct load option in the target table.

  • Including the Table, Comparison transforms into the data flow.
  • Designing the data flow to completely replace the target table during each execution.
  • Including a preload SQL statement to execute before the table loads.

Q39) What is the use of AutoCorrect Load?

Ans: it does not allow duplicated data entering into the target table. It works like Type 1 Insert else Update the rows based on Non-matching and matching data respectively.

Q40) What is the use of Array fetch size?

Ans: Array fetch size indicates the number of rows retrieved in a single request to a source database. The default value is 1000. Higher numbers reduce requests, lowering network traffic, and possibly improve performance. The maximum value is 5000

Q41) What is the use of Case Transform?

Ans: Use the Case transform to simplify branch logic in data flows by consolidating case or decision-making logic into one transform. The transform allows you to split a data set into smaller sets based on logical branches.

Q42) What must you define in order to audit a data flow?

Ans: You must define audit points and audit rules when you want to audit a data flow.
