LUW is a logical unit of work and is the span of time
during which any transaction is updated in all or nothing
manner i.e they've been updated completely ro commited or
thrown away(Roll Back). An Luw is nothing but a database
LUW in database is updated from one screen to another
screen within a transaction which does not last longer and
in SAP LUW, the system perfoms database from one
transaction to another and this last longer and is usually
terminated by the programmer by issuing Commit work
statement.
