1. Go to [IMLN] and identify  the custom function in the [X_UC_FUNCTIONS] lexicon
* Saved Value is a unique 10 character code that is stored in the data base
* Displayed Value is the Function Name as declared in the data base
* Meaning is the product that the Function is intended to be used with

2. Create the function in the data base as a [data base function] returning VARCHAR or NUMBER 
* No parameters may be defined in this function
* Variables can be passed, however, by setting their value prior to calling the custom function
** Variables defined on the IMUC Variables tab are created in the User Calc as V_<''variable name''>
** example:  a Variable identified as __Current Month FTE__ will be identified as __V_CURRENT_MONTH_FTE__ in the SQL code
