DataSource Use in CAF and SAP BW
Integration
A DataSource is data provider from which CAF extracts its data. Technically seen, DataSources are sets of logically-related fields that are provided to enable the transfer of data into flat or multiple flat structures (in the case of hierarchies).
Query Definitions for Extracting Data
The following rules help you to define queries used to extract data from CAF to SAP BW:
Service Type |
Rule |
Entity service |
Queries with name findByMultipleParameters are assumed to have only one possible query to extract data from CAF to SAP BW. |
Application service |
SAP BW extractor methods (operationType=8) that return a collection of data structures and have java.util.Map as an input parameter, are assumed to be queries for extraction data from CAF to SAP BW. The data structure should have a field characterized as RECORDTYPE of dictionary type with a built-in type integer for delta loading support. |
