SAP LUW
Related sequence of programming units, whose execution , for example in
dialog steps or in
remote function calls, can be distributed across multiple
work processes, but whose database changes are updated within a single
database LUW. SAP LUWs are implemented by bundling techniques, in which programming units such as
update function modules or
subroutines are registered in different work processes but executed by a single work process. An SAP LUW is usually started by opening a new
internal session and completed by the
ABAP SQL statement
COMMIT WORK. Changes within one SAP LUW can be undone by the ABAP SQL statement ROLLBACK WORK.
