The user should enter exactly 4 digits.
I created an item text ,*number*,*maximum length*=4
I created this function:
FUNCTION numeric (v in varchar2)RETURN boolean IS
if NOT numeric(:block.item) then
=> when I entered *0123* or *1234* should be acceptable ..but always the message displayed is "invalid item"

in response to
The value 0123 is not a number, but a character. So, your item cannot not be NUMBER, but has to be CHAR.
But it is way easier to use standard Forms functionality for this. Create a Char item with these properties:
Maximum length = 4
Fixed Length = Yes
Format Mask = 9999
