![]() For example, you can define formulas that use the functions of the transformation library for the transformation. The functionality includes a 1:1 assignment of the data, the use of complex functions in formulas and custom programming of transformation rules. This is done using rules that allow any degree of complexity when transforming the data. The transformation allows you to consolidate, clean up and integrate the data, thus synchronizing it and allowing it to be evaluated. With transformations, data loaded within the SAP NetWeaver BW system using the specified interfaces is transferred from a source format to a target format in the data warehouse layers. The data transfer can be triggered by a request from the SAP NetWeaver BW system or by SAP BusinessObjects DataServices or a third party tool. Staging BAPIs are open interfaces, which SAP NetWeaver BusinessObjects DataServices and certified third party tools can use to extract data from older systems. Staging BAPIs (Staging Business Application Programming Interfaces).The data request is controlled from the SAP NetWeaver BW system. The data request is controlled from the SAP NetWeaver BW system.ĭB Connect permits the extraction from and direct access to data located in tables or views of a database management system. UD Connect permits the extraction from and direct access to relational data. Web services permit you to send data to the SAP NetWeaver BW system under external control. The file interface permits the extraction from and direct access to files, such as csv files. These can be SAP application systems or SAP NetWeaver BW systems. The BW service API allows data from SAP systems in standardized form to be extracted and accessed directly. BW Service API (BW Service Application Programming Interface).SAP NetWeaver BW thus allows integration of SAP data and non-SAP data. Transformations allow you to run a technical cleanup and to consolidate the data.Įxtraction and transfer processes to the initial layer in SAP NetWeaver BW as well as direct access to data are possible using various interfaces, depending on the origin and format of the data. Sources for the Enterprise Data Warehouse can be operational, relational datasets (for example in SAP systems), files or older systems. In this case the data is integrated virtually into the Enterprise Data Warehouse. Depending on the data warehousing strategy for your application scenario, you can extract the data from the source and load it into the SAP NetWeaver BW system, or directly access the data in the source, without storing it physically in the Enterprise Data Warehouse. SAP NetWeaver BW offers flexible ways of integrating data from various sources.
