There are many industry specific solutions that SAP provides apart from the list of modules above which is ever growing.
Q6.What is Meta data, Master data and Transaction data?
Ans: Meta Data: Meta Data is data about Data. It tells you about the structure of data or MetaObjects.

Transaction Data: This is data related to day to day transactions.
Q7. Can we run business warehouse without SAP R/3 implementation?
Ans: Yes, you can run business warehouse without R/3 implementation. You have to simply transfer structures associated with business warehouse data sources (ODS table, Infocube) to the inbound data files or use third party tools to connect your flat files and other data sources.
Ans: Variables are used in different application
Ans:
Ans: OLAP: OLAP stands for Online Analytical Processing it is a reporting tool configured to understand your database schema, dimensions and composition facts
Data Mining: It is an analytic process to explore data in search of consistent patterns or systematic relationship between variables.
Ans: Three stages of data-mining includes
Ans: Different layers in R/3 system includes:
Ans: To create a table in the data dictionary, you have to follow these steps:
Ans: AWB stands for Administrator Workbench. It is a tool for monitoring, controlling and maintaining all the processes connected with data staging and processing in the business information warehousing.
Ans: Bex means Business Explorer. It allows end user to locate reports, analyze information, view reports and can execute queries. The queries in workbook can be saved to their respective roles in the Bex browser. It has following components Bex analyzer, Bex Map and Bex web.
Ans: An ODS object serves to store debugged and consolidated transaction data on a document level. It defines a consolidated dataset from one or more info-sources. This data-set can be evaluated with a Bex query or Infoset query. The data of an ODS object can be updated with a delta update into InfoCubes or other ODS object in the same system or across systems. In contrast to multi-dimensional data storage with InfoCubes, the data in ODS object is stored in transparent, flat database tables.
Ans: Data Element: It is an intermediate object between domain and table type
Domain: It defines the attributes such as length, type, and possible value range
Ans: To use parameter IDs, you need to “set” values in the global memory area and then “get” values from this parameter ID memory area. In the case of the online program, you have to “Set” values from screen fields, and you will “get” these values for screen fields.
Ans:
Ans: BDC stand for Batch Data Communication. The methods of BDC are:
Ans: The baseline date is the date from which the payment terms apply. Usually, it is the document date on the invoice but can also be the date of entry or posting date from the ledger.
Ans: In certain industries, it is not possible to create new master records for every vendor trading partner. One-time vendor enables for a dummy vendor code to be used on invoice entry and the information that is normally stored in the vendor master, is keyed on the invoice itself.
Ans: The difference between the residual and partial payment includes:
Ans: It is the standard data type object; it exists only during the run time of the program.
Check the table will be at field level checking
Value table will be at domain level checking
Transparent table will exist with the same structure both in the dictionary as well as in the database exactly with the same data and fields.
Ans: The application layer of a R/3 system is made up of the application server and the message server. Application programs in an R/3 system run on application servers. Using the message server, the application servers communicate with presentation components, the database and also with each other. All the data are stored in a centralized server, which is known as a database server.
Ans: Company in SAP is the highest organizational unit for which financial statements like profit and loss statements, balance sheets can be drawn according to the requirement of organizations.

Ans: In the SAP source system, extractors are a data retrieval mechanism. It can fill the extract structure of a data source with the data from the SAP source system datasets.
Ans: The star schema consists of the fact tables and the dimension tables. The master data related tables are kept in separate a table, which has reference to the characteristics in the dimension tables. These separate tables for master data are termed as the Extended Star Schema.
Ans: The approach to writing BDC program is to
Create recording
Convert the legacy system data to a flat file into the internal table referred as “Conversion.”
Transfer the Flat file into the SAP system called “SAP Data Transfer.”
Depending upon the BDC type call transaction or create sessions.
Ans: Business Warehouse uses a data warehouse and OLAP concepts for analyzing and storing data While the R/3 was intended for transaction processing. You can get the same analysis out of R/3, but it would be easier from a BW.
Ans: To deal with communication, you can use two types of services such as:
Message Service: In order to exchange short internal messages, this service is used by the application servers
Gateway Service: This service allows communication between R/3 and external applications using CPI-C protocol.
Ans: “Reason Codes” are tags that can be allocated to describe under/overpayments during the allocation of incoming customer payments. They should not be mixed up with “void reason codes” used when outgoing cheques are produced.
Ans: Pooled tables are used to store control data. Several pooled tables can be united to form a table pool. Table tool is a physical table on the database in which all the records of the allocated pooled tables are stored.
