Hi Madhu,
Check this from Qlikview help (F1) file.
The ApplyMap function is used for mapping any expression to a previously loaded mapping table. The syntax is:
applymap('mapname', expr [ , defaultexpr ] )
where:
mapname is the name of a mapping table that has previously been created through the mapping load or the mapping select statement (see Mapping). Its name must be enclosed by single, straight Quotation Marks in Scripting.
expr is the expression, the result of which should be mapped.
defaultexpr is an optional expression which will be used as a default mapping value if the mapping table does not contain a matching value for expr. If no default value is given, the value of expr will be returned as is.
Examples:
// Assume the following mapping table:
map1:
mapping load * inline [
x, y
1, one
2, two
3, three ] ;
ApplyMap ('map1', 2 ) returns ' two'
ApplyMap ('map1', 4 ) returns 4
ApplyMap ('map1', 5, 'xxx') returns 'xxx'
ApplyMap ('map1', 1, 'xxx') returns 'one'
ApplyMap ('map1', 5, null( ) ) returns NULL
ApplyMap ('map1', 3, null( ) ) returns 'three'
