Maintaining Data Transfer Control Parameters for DataSources 

Use

In the BW scheduler, you can specify control parameters for data transfer for individual DataSources. You can do this by choosing Schedulerà DataSource. Default Settings for Data transfer. This allows you to update transaction data to larger data packages in the PSA, for example. Smaller packages guarantee faster processing when you update master data in the dialog.

You can define the following parameters for DataSources and file DataSources from SAP source systems:

Control Parameter	Update Mode
Size of data package	For all possible update modes
Frequency with which the status IDocs are sent	For all possible update modes

You can still define the following parameters for DataSources from SAP source systems:

Control Parameter	Update Mode
Maximum number of data packages per request  If there is an initial value, the system performs the data transfer according to the settings in the source system. A value 0 overwrites the setting in the source system. In this case, there is no limit.	For delta and repeat requests

Integration

DataSources from SAP Source Systems

The settings you made in the Scheduler override the settings made in extractor-customizing for SAP source systems for a particular DataSource and a particular update method.

Normally, you maintain the control parameters for data transfer from an SAP source system in the Customizing transaction for the extractors. You go to the Customizing transaction for the extractors from the context menu in the corresponding source system in the source system tree in Data Warehousing Workbench. Choose General Settings à Maintaining Control Parameters for Data Transfer to display or change the settings for the data transfer on source system level.

File DataSources

Use the settings that you made in the Scheduler to override settings you have made for DataSources in Customizing under Business Warehouse à Links To Other Systems à Maintain Control Parameters For Data Transfer.
