selection.
It has the following prerequisites:

The conversion program RSWN_SET_APP_OBJ_KEY_HASH has run successfully.
The APP_OBJ_KEY_HASH column is filled for all lines of table SWN_NOTIF.
If these prerequisites are not met, you cannot activate the optimized
delta selection, because otherwise the UWL and Duet can no longer be
supplied with data (work items) and e-mail notifications can no longer
be sent.
