Form validations play a crucial role in ensuring data quality and enforcing business processes in Dynamics 365 CE. With multiple options available, it's essential to choose the right approach based on the scenario.
 
Here’s a quick guide to help you decide:
 
✅ Business Rules

Great for complex UI interactions like showing/hiding sections or fields.
 
 
🛠️ Plugins
The go-to option for server-side, centralized validations.
 
Run at Pre-Operation or Pre-Validation stages, ensuring data consistency.
