You can take a substring from the end of a string by using the length function to calculate the starting point. Let n be the number of characters at the end you want to get:

substring(${field_name}, length(${field_name}) - (n-1), n)


If I want to get the last 4 digits of the license key for example:

substring(${license_key}, length(${license_key}) - 3, 4)


This works regardless of the length of the string.

Chat Tip: Many use cases for table calcs require multiple functions, combined in interesting ways. Think about how you can use the pieces you have to do what you want.
