SAP LUW
Related sequence of programming units, whose execution, for example in dialog steps or in Remote Function Calls can be distributed across several work processes , but their database changes are updated within one single database LUW. SAP LUWs are implemented by bundling techniques, in which programming units such as update function modules or sub-routines are registered in different work processes but executed by one single work process. An SAP LUW is usually started by opening a new internal session and completed by the Open SQLstatement COMMIT WORK. Changes within one SAP LUW can be undone by the open SQLstatement ROLLBACK WORK.
