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.

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.

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.

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.

Global temporary tables are temporary table for perticular session.
Global temporary tables are two types,
1.Transaction wise temporary table
2.Session wise temporary tables.
In transaction wise temporary tables we will use on commit delete rows keyword, which delete the data whenever we do commit.
In session wise temporary table we will use on commit preserve rows keyword, which preserve the data till the end of that session.

format trigger:
When we want hide or display the objects in in layout model dynamically we can use format trigger. format trigger we can write in item level
action trigger:
When a button selectd procedure executed new report open.

ZERO_DIVISOR,
INVALID_CURSOR,
CURSOR_ALREADY_OPEN

This segment will be paired with the balancing segment when generating account balances for the Retained Earnings account, Unrealized Gains or Losses accounts, and the Cumulative Translation Adjustment account.

Not possible.

Yes, Auto Accounting determines the general ledger accounts for transactions that are entered manually or import using Auto-invoice.

1. natutal account while creating Ap invoice should be
Asset clearing account
2. Enable track as asset in AP invoice line distributions
3. The Invoice should be validated, accounted and transfered
to GL.

Note- mass additions will work only if transfer to run
program is run and ap invoice is transfered to GL.

Automatic Offsets, Payables automatically balances invoice and payment distributions that cross balancing segments by creating offsetting entries for each balancing segment.

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

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.

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.

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.

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.

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

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.

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.

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 analysis, often algorithmic; even more often misappropriate called "reporting.

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.

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.

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 carried. Transparent table:
Exists with the same structure both in dictionary as well as in database exactly with the same data and fields.
