Let's look at the steps to make the field read-only from business rules.
- Create or edit a rule.
- Define the population for which this rule will apply in the conditions.
- In the Regions and Fields filter, search or navigate to the Business Unit field and set the Read Only property to Read Only. Note that the read-only property is specific to some pages and fields and may not be available for all fields on the same page.
