why we use matchcode object?without using match codes how
we use search helps?

Answer Posted / salil b

Matchcode object is used to add search help for a particular field in a selection screen.

However there is an alternate method to create search help without using Matchcode object.
Use Function module, F4INT_INT_TABLE_VALUE_REQUEST in an event AT SELECTION-SCREEN on VALUE REQUEST FOR and pass necessary parameters to this FM(See the where used list of this FM for many examples)
