From Release 4.0A you can transfer data from sales documents using the Data Transfer Workbench in Direct Input Procedures.
You can either transfer data with Direct Input immediately, or in the background. SAP recommends using direct input in the background. This prevents overloading the system and provides the following advantages:
To find the Data Transfer Workbench, go to Customizing for Sales and Distribution Data Transfer and Archiving --> Data transfer -- Data transfer workbench: Sales documents.
You can find further information on the Data Transfer Workbench, in the main screen for the Data Transfer Workbench in Help --> Extended help.
You will also find more information about transferring data from sales documents in the Implementation Guidelines under Data transfer workbench: Sales documents .
