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.
5. 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.
6. 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.
7. What is IDES?
International Demonstration and Education System. A sample application provided
for faster learning and implementation.
8. 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.
9. 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.
10. 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.
11. 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).
12. 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.
