Answer Posted / archana satpathy
Place holder column is a local function. By default it
returns the value assigned to it. For eg
:CP_TEST_PH := 'INDIA' will return the string 'INDIA'. You
can write code in the place holder formula by just writing
what you want to return (return 'INDIA'). In that case you
dont have to assign anything to :CP_TEST_PH anywhere. Just
make sure while creating your Place Holder column, it
returns correct datatype of adequate size.
