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.
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.
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.
What is IDES
International Demonstration and Education System. A sample application provided for faster learning and implementation.
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.
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.
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.
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).
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.
What are datasets
The sequential files (processed on application server) are called datasets. They are used for file handling in SAP.
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.
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.
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.
