Answer / avijit

Any parameter which depends upon another parameter for it's value is called as dependent parameter.
That means the parameter can not be evaluated unless the parent parameter is resolved first.

Exemple :

$PROC_DATE : now()
$EXE_DATE : string_substring($PROC_DATE,1,8)

Here as you can see EXE_DATE depends on te PROC_DATE to be available first.
