Auto-Filling DFF Based on Legal Entity or Asset Book

Hello everyone,

Thank you in advance for your help, I have a question regarding Descriptive Flexfields (DFF). In our setup, we have a DFF for the region, and I need to know if there's a way to automatically fill this DFF based on the legal entity or asset book of each country.

Specifically, we want the region DFF to be populated automatically when a legal entity or asset book is selected. Is there a configuration or rule that can be set up to achieve this? Any guidance or examples would be greatly appreciated.

Best regards,
Paul
