SAP BW Extractor
extractor is the program in SAP ERP which can be activated to prepare and
capture the data through an extract structure for transfer to BW. The extractor can be the result of a standard
DataSource or a custom built DataSource. It can describe a full load or a delta
load process of different types.
The data transfer section of the program is
remotely called from SAP BW. When the extractor is a delta type, it also runs
to populate the delta queue with new and changed records. The data transfer
remote call then transfers the data to SAP BW.
