How can I limit access to specific variables for my colleague?

First of all, invite a user, create or change a permission group and add him there. Navigate to Lending Setup > Variables and click on the variable you want to limit access to or create a new one. Find “Variable Permissions” and set it active. Apply the setting “Fully Hidden” for the users' permission group. Now if you have this variable added to application tabs in Loan Origination System or added to Decision Engine strategies, a user with a limited permission variable view will see its values masked with asterisks.
