About Lookup Tables

Lookup tables define a set of key-value (name-value) pairs. During run time, these key-value pairs are used to translate the passed in key to the associated value.

A lookup table is similar to a function that has one input string parameter (the source value to translate) and a string return value (the result of the translation). In the Mapping Editor, a lookup table can be dragged onto a mapping rule in the same way that a function can be.

Lookup tables are available to use in any map in the project where they were defined.
