A BW datasource is a structure, which is created in the source system and replicated to the BW system. Maintaining a datasource in a source system is doing any changes related to the datasource. It could be adding/deleting fields or checking the flags in the datasource like the hide and selection flag. Also, if the datasource is provided in the LO Cockpit, changes can be made there too depending on how the extraction of data is made for that datasource. Extraction could be of flat file extraction or of multiple flat structures ie., hierarchies.
There are basically two types of DataSources:
- DataSource for transaction data
- DataSource for master data
- DataSource for attributes
- DataSource for texts
- DataSource for hierarchies
Data sources are used to get data into the BW system.
