XML DataSource (BW DataSource with SOAP Connection) 

Definition

DataSource that is generated in SAP BW on the basis of a file-DataSource and that can be used to push data to SAP BW.

Use

With the help of the generated XML DataSource, you can transfer XML data into the SAP BW delta queue in order to continue to process it and to post it into the data targets you want.

Integration

The starting point for the generation of the XML DataSource is a file DataSource.  It is used to characterize the data that is to be sent to the SAP BW.

You create the file DataSource using the definition of an InfoSource with flexible updating for a file source system. When the transfer rules are activated, you generate the file DataSource with the transfer structure. Now you can generate an XML DataSource in the maintenance of the transfer rules of the file DataSource using Extras → Create BW DataSource with SOAP Connection. This has the following properties:

·        It is generated in a new namespace (<xml-datasource> = 6a<file-datasource>.

·        The BW system itself is its source system (myself-connection)

·        It is only intended for the loading of delta records, since the inbound queue is the delta queue in BW.

·        It has an interface for supplying the delta queue.

In doing so, the SAPI interface for supplying the delta queue is encapsulated by a DataSource-specific, RFC-compatible function module, which is generated for this purpose for the DataSource.  Based on the RFC capability, the function module can be addressed externally (for example through a Web service, the http request handler of the SOAP service or the XI proxy runtime).

The function module has the following properties:

Property	Technical name
Function group naming convention	/BIO/QI<xml-datasource>
Function module naming convention	/BIO/QI<xml-datasource>_RFC
Import parameter	<xml-datasource>
Table parameter	data

·        The XML DataSource extraction structure is generated to suit the file DataSource transfer structure.

·        The selectability of fields and the delta process are based on the file DataSource.

If you have established the update mode Additives Delta for the file DataSource, the XML DataSource uses the ABR delta process (after, before, reverse), otherwise the XML DataSource uses the AIM delta process (after image).
