I need to make some modifications to a field in our SIS extract. These changes would be to an existing field but the logic will be different. How do I test this change without changing the data of all of my users?
A possible solution:
Instead of changing the existing field that you are using, change a field that is empty or unused; if one doesn't exist work with support to add one. Then you'll be able to compare the fields side-by-side with your current population. Once you're happy with the results then you can change the logic of the original field.
