What should a business practitioner do if the required field in the Expression Editor is disabled?

The correct approach when a required field in the Expression Editor is disabled is to switch the Expression Editor to Advanced Mode. This option unlocks additional capabilities and functionalities that may not be available in the standard mode. In Advanced Mode, the practitioner can gain access to a broader range of tools and settings, allowing for a more detailed and flexible configuration of expressions.

In many applications, certain features or options might be restricted in basic modes to simplify the user experience. By transitioning to Advanced Mode, users can often manipulate or work with required fields that are otherwise inaccessible, enabling them to create more complex expressions tailored to their needs. This is essential for effective data handling and maximizing the use of the platform's features.
