Flexible reporting and analysis tool for evaluating and interpreting the data.

Business data integrated, transformed, and consolidated in Sap BI.

Relevant business data from SAP systems and all data sources can be integrated, transformed, and consolidated in Sap BI. Consolidate: the consolidation of data from multiple sources into a centralized system.Data integration involves combining data residing in different sources and providing users with a unified view of these data.A data warehouse (DW or DWH) is a database used for reporting and data analysis. It is a central repository of data. Stores current & historic data.A Data Warehouse is a subject-oriented, integrated, time-variant and nonvolatile collection of data in order to support management decisions, Bill Inmon (1996).7History of SAP BISAP launched the product in 1997 by the name Business information Warehouse (BIW), Version 1. 2A

Product Name Changed to Business Warehouse (BW) with version 3.0A

Named Business Intelligence BI with version 7.0

Key Functionalities of SAP BI ETL Process The process of the extracting data from Source systems and making it useful for our needs is ETL

ETL is not a one time process as new data is added to warehouse periodically . ETL is integral, ongoing, and recurring part of the warehouse. ETL Creates a logical and physical separation between the source system and data warehouse.10SAP systems (S-API Service Application Programming Interface)BI systemsFlat files Database management systems (DB Connect)Relational or multidimensional sources (UD Connect)Web Services

Source Systems SAP Source Systems: Connects SAP systems to SAP NetWeaver BI through the BI Service API (S-API)DB connect (Database connect) used to extract data from the database management systems Ex (Danaos & Afsys in SCI)UD Connect (Universal data Connect) converts and transfers multidimensional data as flat data. This technology runs on the J2EE Engine and supports the J2EE Connector Architecture.File: SAP supports automatic import of files in CSV or ASCII format for flat files.Web Services: A Simple Object Access Protocol (SOAP) service is used to read XML data and to store it in a the BI server. In many cases, SAP Exchange Infrastructure (XI) is leveraged when loading XML-based data.Staging BAPIs(Staging Business Application Programming Interfaces)Staging BAPIs are open interfaces from which third party tools can extract data from older systems. The data transfer can be triggered by a request from the SAP NetWeaver BI system or by a third party tool.

1)DataSource for transaction data2) DataSource for master data

DATASOURCEDataSources for transferring data from SAP source systems are defined in the source system; the relevant information of the DataSources is copied to the BI system by replicationWhen you activate the DataSource, the system generates a PSA table in the entry layer of BI. You can then load data into the PSA.15PSA The Persistent Staging Area (PSA) is the storage area for data from the source systems in BI.

The requested data is saved, unchanged from the source system.

Starting point (entrance) of data into BI systemRequest data is stored in the transfer structure format in transparent, in BI.PSA also allows you to check and change the data before the update into data targets16 DSOA DataStore object serves as a storage location for consolidated and cleansed data.

The data in DataStore objects is stored in transparent, flat database tables.

This data can be evaluated using a BEx query. Contain 1) Key Fields (Ex Doc number, item etc 2) Data Fields Determine the sales amount for customers located in New York with Material Group ABC in the year 2011

Dimensions /CharacteristicsBrowsing the Dimension tablesAccess the Customer dimension table and select all records with City = New YorkAccess the Material Dimension and select all records with material Group = ABCAccess the Time Dimension Table and select all records with Year =2011As a result of these browsing activities, there are a number of key values(Customer ID, Material ID , Time Code ID) from each dimension table is affectedAccessing the fact table From all the key values evaluated, select all the records in the fact table that have these values in common in the fact table record key.Characteristic values are stored in dimension tables.18
