Documentation

Definition

Procedure used when accessing data.

Use

The DataSource concept in BW offers an extendable framework for integrating diverse data access methods. To do this, certain interfaces have to be implemented in ABAP OO, and the method must be declared using the collective view RSDSACCESS. In addition to this, the method must also be assigned to one or more source system types.

There are two types of access method:

• Adapter
• Conversion into a particular data format

Dependencies

Example

GUI_UPLOAD:     Extraction of data from a file from the client host.

OPEN_DS:     Extraction of data from a file from the application server.

ASCII:     Conversion of fixed-length data to the BW structure.
