When you need to validate and normalize field values against code sets, you can use lookup functions to execute the mapping. This is useful when you don’t have the data immediately available.

There are various options for performing lookups. In IguanaX, you can use:

 1) Codemap library to perform lookups against local code sets you define.

With the Codemap Library you can:

  • Confirm an incoming value is contained in a code set.

  • Translate from one value or code set to another.

 2) Perform an external lookup against a database or API

  • Useful when you don’t have the data within the current system; can look them up elsewhere.

  • If these lookups are done across various interfaces, they are best stored in a library.
