DataSources
New DataSources have been created for NW 2004s BI Content Add-On 2 and SRM 5.0. These are described here, along with their extraction logic.
The following graphic shows the data flow from the DataSources to the DataStore objects
Structure
Each DataSource has an extraction structure and a data extractor. Generally, this is an RFC-capable function module.
There are two types of extraction: Specific extraction and generic extraction:
Specific extraction is strongly oriented towards the data model of the BI System and the necessary extract structure. It executes DataSource-specific processing steps.
The logic contained within the generic extraction is implemented centrally and can therefore be reused by the specific extraction modules. The generic extraction deals with access to the SRM database and is similar for each DataSource.
Generic and specific extraction
Extraction logic in detail
Data extraction involves the following six function modules:
InitLoad
InitLoad is called as soon as an initial upload is started in the BI System. In other words, it is executed when data is loaded into the BI System for the first time. The module can restrict the data extraction according to filter criteria that were defined in BI during extraction (for example, extract the data for a particular timeframe). InitLoad packages the data before it is transferred to the BI System.
DeltaLoad
DeltaLoad is called when a document is modified in the SRM System. The module writes data that has accumulated since the initial loading to a delta queue.
Data Collector
The Collector reads the required data from the database in the source system. For performance reasons, the data is then buffered in system-internal tables. The tables have the same structure as in the database. This saves time and effort, because data conversion is kept to a minimum.
Data Consolidator
The Consolidator groups data that belongs together from a business point of view. The consolidated data is stored in internal tables and is prepared for further processing.
Data Normalizer
The Denormalizer prepares the source data for the BI System. It calculates key figures that are required for the report but are not contained on the database and converts data types in the source system to data types of the BI System. Depending on the BI data model, the system now decides how each row is filled with data.
Data Mapper
During mapping of the data, the system defines which fields of the denormalized data structure are assigned to the fields of the extract structure. In this way, flat and one-dimensional lines are generated from the data.
The following table shows the technical names of the function modules of the individual DataSources:
