Documentation
Definition
If you select this setting, data is not extracted from the Persistent Staging Area (PSA) of the DataSource. Instead the data is requested directly from the data source at the runtime of the DTP.
Use
You can load the data for all source systems without PSA directly into the InfoProvider, if you extract small quantities of data using a DTP with the 'Full' extraction mode (for example, small quantities of master data).
For ODP source systems you can also load mass data and delta directly into the InfoProvider.
Dependencies
You need not create an InfoPackage in order to extract data from the source.
Note that the file is available on the server when you are extracting from a file source system.
For all source systems apart from the ODP source system, the data source is accessed in "direct access mode". This has certain implications, especially when extracting from SAPI systems:
- The data is extracted synchronously. This places special requirements on main memory, especially in the remote system.
- The SAPI extractors might behave differently than for asynchronous loading since they are informed by the direct access.
- No SAPI customer enhancements are processed. Fields that were added to the DataSource with append technology are left empty. Exits RSAP0001, exit_saplrsap_001, exit_saplrsap_002 and exit_saplrsap_004 are not executed.
- If errors occur during processing, you need to extract the data again in BW because the PSA is not available in the buffer. This means that it is not possible to create a delta.
- The filter in the DTP only contains fields that are allowed as selection fields by the DataSource. If a PSA is available, you can use all the fields for filtering in the DTP.
