Processing Modes
© SAP AG
Foreground Display all dialog steps
Display errors only Display dialog steps only for error or
termination messages
Background Dialog steps not displayed, processing
takes place in the background
In the ‘Process in foreground’ mode, all screens of a transaction are displayed. The authorizations of the
user doing the processing apply. If a session terminates abnormally in test mode, you can use the
Restart function to branch directly to the session overview (where you can restart the processing).
In the ‘Display errors only’ mode, screens are displayed only when an error occurs. A transaction
contains an error if a type E (error) or type A (termination) dialog message is output. The authorizations
of the user doing the processing apply.
In the ‘Process in background’ mode, the session is processed in the background. Your screen is
available for input as soon as the session has been passed to the background control system. The
authorizations of the BDC user specified in the header part of the session apply.
When processing a session, the update mode is always synchronous (i.e. the next transaction is called
only when the update for the preceding transaction has been completed).
