SAP Tutorials

IDoc (Intermediate Document) is used in SAP to transfer data between two systems. It is a specific instance of a data structure called the IDoc Type, whose processing logic is defined in the IDoc Interface.

An index is a technique used to locate needed records in a database table quickly. BW uses two types of indices: B-tree indices for regular database tables and bitmap indices for fact tables and aggregate tables.

InfoAreas are used to organize InfoCubes and InfoObjects. Each InfoCube is assigned to an InfoArea. Through an InfoObject Catalog, each InfoObject is assigned to an InfoArea as well. The maximum number of characters allowed for the technical name is 30.

An InfoCube is a fact table and its associated dimension tables in the star schema. The maximum number of characters allowed for the technical name is 30.

InfoCube compression is a procedure used to aggregate multiple data loads at the request level.

In BW, key figures and characteristics are collectively called InfoObjects.

InfoObject Catalogs organize InfoObjects. Two types of InfoObject Catalogs exist: one for characteristics, and one for key figures. The maximum number of characters allowed for the technical name is 30.

An InfoPackage specifies when and how to load data from a given source system. BW generates a 30-digit code starting with ZPAK as an InfoPackage’s technical name.

An InfoSource is a structure in which InfoObjects are logically grouped together. InfoCubes and characteristics interact with InfoSources to get source system data. The maximum number of characters allowed for the technical name is 32.
