Data Prep mapping functions

Data Prep functions can be used to compute and calculate values based on what is entered in source fields.

Fields

A field name can be any legal identifier - an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign ($), or the underscore character (_). Variable names are also case sensitive.

If a field name does not follow this convention, the field name must be wrapped with ${}. So, for example, if the field name is “First Name” or “First.Name”, then the name must be wrapped like ${First Name} or ${First.Name} respectively.

Additionally, if a field name is any of the following reserved keywords, it must be wrapped with ${}:

new, mod, or, break, var, lt, for, false, while, eq, gt, div, not, null, continue, else, and, ne, true, le, if, ge, return

Data within sub-fields can be accessed by using the dot notation. For example, if there was a name object, to access the firstName field, use name.firstName.
