èAn InfoSource is a set of information that logically belongs together, summarized into a single unit. It prepares consolidated data for updating to the data targets.
èInfoSources contain either transaction data or master data (attributes, texts and hierarchies).
èAn InfoSource comprises of Communication structure and Transfer structure.
èThe set of InfoObjects that logically belong together form the communication structure. The transfer structure is used to transfer data to the BW system. The data is transferred 1:1 from the transfer structure of the source system into the BW transfer structure.
èTypes of InfoSources
lInfoSources with flexible updating
lInfoSources with direct updating
èFlexible Update
lHere data from the communication structure is loaded into the data targets (InfoCubes, ODS objects, master data) using update rules.
lSeveral data targets can be defined by one InfoSource.
lThe InfoSource can contain transaction data and master data.
èDirect Update
lMaster data (characteristics with attributes, texts or hierarchies) of an InfoObject can be updated directly (without update rules, only using transfer rules) to the master data table with an InfoSource with direct updating.
