Creating functions in BPM Composer

Question

In JDeveloper (or BPM Studio), opening an existing dictionary, I can see the following tabs: Facts, Functions, Globals, Bucketsets, Links, Decision Functions and Rulesets.
However, in BPM Composer, I don't have Functions tab (see http://docs.oracle.com/cd/E28280_01/user.1111/e15177/business_rules_bpmcu.htm).  (same for links and decision functions) ....
Is it because business analysts are not expected (or supposed) to write functions?  This seems to have an obvious answer, but I would really appreciate if someone could confirm it.
Thank you,

Answer 1

if you are just going to start entries then you can .
But i have posted then Use replace function in SQL
SQL Syntax:
      REPLACE( string1, string2, string3 ) 
Parameters:
    string1
Any character string or binary expression that can contain the string from string2.
string2
Any character string or binary expression. This string is searching in string1.
string3
Any character string or binary expression. This string replace all occurrence of string2.
May it will work
Thanks
