SAP Interview Questions

SAP Interview Questions

1.Explain the concept of “Business Content” in SAP Business Information Warehouse?
Business Content is a pre-configured set of role and task-relevant information models based on consistent Metadata in the SAP Business Information Warehouse. Business Content provides selected roles within a company with the information they need to carry out their tasks. These information models essentially contain roles, workbooks, queries, InfoSources, InfoCubes, key figures, characteristics, update rules and extractors for SAP R/3, mySAP.com Business Applications and other selected applications.

2.Why do you usually choose to implement SAP?
There are number of technical reasons numbers of companies are planning to implement SAP. It’s highly configurable, highly secure data handling, min data redundancy, max data consistency, you can capitalize on economics of sales like purchasing, tight integration-cross function.

3.What is WF and its importance?
Business Work Flow: Tool for automatic control and execution of cross-application processes. This involves coordinating the persons involved, the work steps required, the data, which needs to be processed (business objects). The main advantage is reduction in throughput times and the costs involved in managing business processes. Transparency and quality are enhanced by its use.

4.What is SAP R/3?
A third generation set of highly integrated software modules that performs common business function based on multinational leading practice. Takes care of any enterprise however diverse in operation, spread over the world. In R/3 system all the three servers like presentation, application server and database server are located at different system.

5.What are presentation, application and database servers in SAP R/3?

The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers. The application servers communicate with the presentation components, the database, and also with each other, using the message server. All the data are stored in a centralized server. This server is called database server.

6.Different types of ERP ?

SAP, BAAN, JD Edwards, Oracle Financials, Siebel, PeopleSoft. Among all the ERP’s most of the companies implemented or trying to implement SAP because of number of advantages aver other ERP packages.

7.What should be the approach for writing a BDC program?

Convert the legacy system data to a flat file and convert flat file into internal table. Transfer the flat file into sap system called “sap data transfer”. Call transaction(Write the program explicitly) or create sessions (sessions are created and processed ,if success data will transfer).

8.Explain open SQL vs native SQL?

ABAP Native SQL allows you to include database-specific SQL statements in an ABAP program. Most ABAP programs containing database-specific SQL statements do not run with different databases. If different databases are involved, use Open SQL. To execute ABAP Native SQL in an ABAP program, use the statement EXEC. Open SQL (Subset of standard SQL statements), allows you to access all database tables available in the R/3 System, regardless of the manufacturer. To avoid conflicts between database tables and to keep ABAP programs independent from the database system used, SAP has generated its own set of SQL statements known as Open SQL.

9.What are datasets?

The sequential files (processed on application server) are called datasets. They are used for file handling in SAP.

10.What are internal tables check table, value table, and transparent table?

Internal table: It is a standard data type object, which exists only during the runtime of the program. Check table: Check table will be at field level checking. Value table: Value table will be at domain level checking ex: scarr table is check table for carrid. Transparent table: - Exists with the same structure both in dictionary as well as in database exactly with the same data and fields.

11.What are the major benefits of reporting with BW over R/3? Would it be sufficient just to Web-enable R/3 Reports?

Performance — Heavy reporting along with regular OLTP transactions can produce a lot of load both on the R/3 and the database (cpu, memory, disks, etc). Just take a look at the load put on your system during a month end, quarter end, or year-end — now imagine that occurring even more frequently. Data analysis — BW uses a Data Warehouse and OLAP concepts for storing and analyzing data, where R/3 was designed for transaction processing. With a lot of work you can get the same analysis out of R/3 but most likely would be easier from a BW.

12.How can an ERP such as SAP help a business owner learn more about how business operates?

In order to use an ERP system, a business person must understand the business processes and how they work together from one functional area to the other. This knowledge gives the student a much deeper understanding of how a business operates. Using SAP as a tool to learn about ERP systems will require that the people understand the business processes and how they integrate.

13.What is the difference between OLAP and Data Mining?

OLAP - On line Analytical processing is a reporting tool configured to understand your database schema ,composition facts and dimensions . By simple point-n-clicking, a user can run any number of canned or user-designed reports without having to know anything of SQL or the schema. Because of that prior configuration, the OLAP engine “builds” and executes the appropriate SQL. Mining is to build the application to specifically look at detailed analyses, often algorithmic; even more often misappropriate called “reporting.

14.What is “Extended Star Schema” and how did it emerge?

The Star Schema consists of the Dimension Tables and the Fact Table. The Master Data related tables are kept in separate tables, which has reference to the characteristics in the dimension table(s). These separate tables for master data is termed as the Extended Star Schema.

15.Define Meta data, Master data and Transaction data ?

Meta Data: Data that describes the structure of data or MetaObjects is called Metadata. In other words data about data is known as Meta Data. Master Data: Master data is data that remains unchanged over a long period of time. It contains information that is always needed in the same way. Characteristics can bear master data in BW. With master data you are dealing with attributes, texts or hierarchies. Transaction data: Data relating to the day-to-day transactions is the Transaction data.

16.Name some drawbacks of SAP ?

Interfaces are huge problem, Determine where master data resides, Expensive, very complex, demands highly trained staff, lengthy implementation time.

17.What is Bex?

Bex stands for Business Explorer. Bex enables end user to locate reports, view reports, analyze information and can execute queries. The queries in workbook can be saved to there respective roles in the Bex browser. Bex has the following components: Bex Browser, Bex analyzer, Bex Map, Bex Web.

18.What are variables?

Variables are parameters of a query that are set in the parameter query definition and are not filled with values until the queries are inserted into workbooks. There are different types of variables which are used in different application: Characteristics variables, Hierarchies and hierarchy node, Texts, Formulas, Processing types, User entry/Default type, Replacment Path.

19.What is AWB?. What is its purpose?

AWB stands for Administrator WorkBench. AWB is a tool for controlling, monitoring and maintaining all the processes connected with data staging and processing in the business information whearhousing.

20.What is the significance of ODS in BIW?

An ODS Object serves to store consolidated and debugged transaction data on a document level (atomic level). It describes a consolidated dataset from one or more InfoSources. This dataset can be analyzed with a BEx Query or InfoSet Query. The data of an ODS Object can be updated with a delta update into InfoCubes and/or other ODS Objects in the same system or across systems. In contrast to multi-dimensional data storage with InfoCubes, the data in ODS Objects is stored in transparent, flat database tables.

21.What are the different types of source system?

SAP R/3 Source Systems, SAP BW, Flat Files and External Systems.

22.What is Extractor?

Extractors is a data retrieval mechanisms in the SAP source system. Which can fill the extract structure of a data source with the data from the SAP source system datasets. The extractor may be able to supply data to more fields than exist in the extract structure.

23.Describe how SAP handles Memory Management?

ST02 / ST03 In general via table buffers, you could go into the whole Work Process, roll in, roll out, heap (private) memory, etc. However just as a Unix or DBA admin would know, is you look this up when needed for the exact specifics.

24.Describe where they would look at the buffer statistics, and what steps they would use to adjust them?

ST02, RZ10 ...

25.Can BW run without a SAP R/3 implementation?

Certainly. You can run BW without R/3 implementation. You can use pre-defined business content in BW using your non-SAP data. Here you simply need to map the transfer structures associated with BW data sources (InfoCubes, ODS tables) to the inbound data files or use 3rd part tool to connect your flat files and other data sources and load data in BW. Several third party ETL products such as Acta, Infomatica, DataStage and others will have been certified to load data in BW.

26.What is IDES?

International Demonstration and Education System. A sample application provided for faster learning and implementation.

27.Describe how to setup a printer in SAP or where they would look to research why a user/users can not print?

SPAD, SP01, SM50, SU01 ...

28.Can you create a table with fields not referring to data elements?

YES. eg:- ITAB LIKE SPFLI.here we are referring to a data object(SPFLI) not data element.
What are the different types of data dictionary objects? tables, structures, views, domains, data elements, lock objects, Match code objects.

29.What should be the approach for writing a BDC program?

STEP 1: CONVERTING THE LEGACY SYSTEM DATA TO A FLAT FILE to internal table CALLED "CONVERSION".
STEP 2: TRANSFERING THE FLAT FILE INTO SAP SYSTEM CALLED "SAP DATA TRANSFER".
STEP 3: DEPENDING UPON THE BDC TYPE
i)call transaction(Write the program explicity)
ii) create sessions (sessions are created and processed.if success data will transfer).

30.What are the problems in processing batch input sessions and How is batch input process different from processing online?

PROBLEMS: i) If the user forgets to opt for keep session then the session will be automatically removed from the session queue(log remains). However if session is processed we may delete it manually.
ii)if session processing fails data will not be transferred to SAP database table.

31.What does an extract statement do in the ABAP program?

Once you have declared the possible record types as field groups and defined their structure, you can fill the extract dataset using the following statements: EXTRACT. When the first EXTRACT statement occurs in a program, the system creates the extract dataset and adds the first extract record to it. In each subsequent EXTRACT statement, the new extract record is added to the dataset EXTRACT HEADER. When you extract the data, the record is filled with the current values of the corresponding fields. As soon as the system has processed the first EXTRACT statement for a field group , the structure of the corresponding extract record in the extract dataset is fixed. You can no longer insert new fields into the field groups and HEADER. If you try to modify one of the field groups afterwards and use it in another EXTRACT statement, a runtime error occurs. By processing EXTRACT statements several times using different field groups, you fill the extract dataset with records of different length and structure. Since you can modify field groups dynamically up to their first usage in an EXTRACT statement, extract datasets provide the advantage that you need not determine the structure at the beginning of the program.

32.Can a transparent table exist in data dictionary but not in the data base physically?

NO. TRANSPARENT TABLE DO EXIST WITH THE SAME STRUCTURE BOTH IN THE DICTIONARY AS WELL AS IN THE DATABASE,EXACTLY WITH THE SAME DATA AND FIELDS.

33.What is the step by step process to create a table in data dictionary?

step 1: creating domains(data type, field length, range).
step 2: creating data elements(properties and type for a table field).
step 3: creating tables(SE11).

A service is a process or group of processes that perform a specific system function and often provide an application-programming interface for other processes to call.

62. What are the roll and page areas?

Roll and page areas are SAP R/3 buffers used to store user contexts (process requests). The SAP dispatcher assigns process requests to work processes as they are queued in the roll and page areas.
Paging area holds data from the application programs.
Roll area holds data from previous dialog steps and data that characterize the user.

63. What are the different layers in R/3 system?

Presentation Layer.
Application Layer.
Database Layer.

64. What are the phases of background processing?

Job Scheduling.
Job Processing.
Job Overview.

65. What components of the R/e system initiate the start of background jobs at the specified time?

The batch scheduler initiates the start of background job. The dispatcher then sends this request to an available background work process for processing.

66. Define Instance.

An instance is an administrative unit in which components of an R/3 systems providing one or more services are grouped together. The services offered by an instance are started and stopped at random. All components are parameterized using a joint instance profile. A central R/3 system consists of a single instance in which all-necessary SAP services are offered. Each instance uses separate buffer areas.

67. From hardware perspective, every information system can be divided into three task areas Presentation, Application Logic and Data Storage.

The R/3 Basis software is highly suitable for use in multi-level client/server architectures.

68. What are R/3 Basis configurations?

A central system with centrally installed presentation software.
Two-level client/server system with rolled out presentation software.
Two-level client/server system. Presentation and Application run on the same computer.
Three-level client/server system. Presentation, Application and database each run on separate computers.

69. What is a Service in SAP terminology?

A service refers to something offered by a s/w component.

70. What is Server in SAP terminology?

A component can consist of one process or a group and is then called the server for the respective service.

71. What is a client in SAP terminology?

A S/W component that uses the service (offered by a s/w component) is called a Client. At the same time these clients may also be servers for other services.

72.What is a SAP system?

The union of all s/w components that are assigned to the same databases is called as a SAP system.

73. What is the means of communications between R/3 and external applications?

The means of communication between R/2,R/3 and external applications is via the CPI-C handler or SAP Gateway, using the CPI-C Protocol.

74. What is the protocol used by SAP Gateway process?

The SAP Gateway process communicates with the clients based on the TCP/IP Protocol.

75. Expand CPI-C.

Common Program Interface Communication.

Spool requests are generated during dialog or background processing and placed in the spool database with information about the printer and print format. The actual data is places in the Tem Se (Temporary Sequential objects).

77. What are different types of Log records?

V1 and V2. V1 must be processed before V2. But, we can have more than one V2 logs.

78. What are the types of Update requests?

An update request can be divided into one primary (V1) and several Secondary update components (V2). Time-critical operations are placed in V1 component and those whose timing is less critical are placed in V2 components. If a V1 update fails, V2 components will not be processed.

79. Explain what is a transaction in SAP terminology.

In SAP terminology, a transaction is series of logically connected dialog steps.

80. Explain how SAP GUI handles output screen for the user.

The SAP front-end s/w can either run on the same computer or on different computers provided for that purpose. User terminal input is accepted by the SAP terminal program SAP GUI, converted to SAP proprietary format and sent to the SAP dispatcher. The dispatcher coordinates the information exchange between the SAP GUIs and the work processes. The dispatcher first places the processing request in request queues, which it then processes. The dispatcher dispatches the requests one after another, to the available work process. The actual processing takes place in the work process. When processing is complete, the result of a work process is returned via the dispatcher to the SAP GUI. The SAP GUI interprets the received data and generates the output screen for the user.

81. What are the layers of data description in R/3?

• The external layer.
• The ABAP/4 layer.
• The database layer.

82. Define external layer?

The external layer is the plane at which the user sees and interacts with the data, that is, the data format in the user interface. This data format is independent of the database system used.

83. Define ABAP/4 layer?

The ABAP/4 layer describes the data formats used by the ABAP/4 processor.

84. Define Database layer?

The database layer describes the data formats used in the database.

85. What is a Data Class?

The Data class determines in which table space the table is stored when it is created in the database.

86. What is a Size Category?

The Size category describes the probable space requirement of the table in the database.

87. How many types of size categories and data classes are there?

There are five size categories (0-4) and 11 data classes only three of which are appropriate for application tables:
• APPL0- Master data (data frequently accessed but rarely updated).
• APPL1- Transaction data (data that is changed frequently).
• APPL2- Organizational data (customizing data that is entered when system is configured and then rarely changed).
The other two types are:
• USR
• USR1 – Intended for customer's own developments.

88. What are control tables?

The values specified for the size category and data class are mapped to database-specific values via control tables.

89. What is the function of the transport system and workbench organizer?

The function of the transport system and the Workbench Organizer is to manage any changes made to objects of the ABAP/4 Development Workbench and to transport these changes between different SAP systems.

90. What is a table pool?

A table pool (or pool) is used to combine several logical tables in the ABAP/4 Dictionary. The definition of a pool consists of at least two key fields and a long argument field (VARDATA).

91. What are pooled tables?

These are logical tables, which must be assigned to a table pool when they are defined. Pooled tables can be used to store control data (such as screen sequences or program parameters).

92. What is a table cluster?

A table cluster combines several logical tables in the ABAP/4 Dictionary. Several logical rows from different cluster tables are brought together in a single physical record. The records from the cluster tables assigned to a cluster are thus stored in a single common table in the database.

93. How can we access the correction and transport system?

Each time you create a new object or change an existing object in the ABAP/4 Dictionary, you branch automatically to the Workbench Organizer or correction and transport system.

94. Which objects are independent transport objects?

Domains, Data elements, Tables, Technical settings for tables, Secondary indexes for transparent tables, Structures, Views, Matchcode objects, Matchcode Ids, Lock objects.

95. How is conversion of data types done between ABAP/4 & DB layer?

101. How can we set the table spaces and extent sizes?

You can specify the extent sizes and the table space (physical storage area in the database) in which a transparent table is to be stored by setting the size category and data class.

102. What is the function of the correction system?

The correction system manages changes to internal system components. Such as objects of the ABAP/4 Dictionary.

103. What are local objects?

Local objects (Dev class$TMP) are independent of correction and transport system.

104. What is a Development class?

Related objects from the ABAP/4 repository are assigned to the same development class. This enables you to correct and transport related objects as a unit.

105. What is a data dictionary?

Data Dictionary is a central source of data in a data management system. Its main function is to support the creation and management of data definitions. It has details about
• What data is contained?
• What are the attributes of the data?
• What is the relationship existing between the various data elements?

106. What is the max no of match code Id's that can be defined for one Match code object?

A match code Id is a one character ID that can be a letter or a number.

107. Can we define our own Match Code ID's for SAP Matchcodes?

Yes, the number 0 to 9 are reserved for us to create our own Match Code Ids for a SAP defined Matchcode object.

108. What is an Update type with reference to a Match code ID?

If the data in one of the base tables of a matchcode ID changes, the matchcode data has to be updated. The update type stipulates when the matchcode is to be updated and how it is to be done. The update type also specifies which method is to be used for Building matchcodes. You must specify the update type when you define a matchcode ID.
