What is difference between synchronous and asynchronous Business Rules?

Hi 
In Business rule

• Synchronous - runs immediately when record changes.

• Asynchronous - runs in background (better for heavy logic).

Hi @kishorchika ,

Synchronous business rules execute immediately and halt user action until they complete, providing instant feedback crucial for validation, while asynchronous business rules run in the background, releasing the user to continue their task without delay and are better for non-critical, time-consuming processes like sending emails. The key difference is blocking behavior: synchronous rules block the user, and asynchronous rules don't.

Synchronous - Executes immediately and waits for the operation to complete before processing next steps

Asynchronous - Run in the background and proceed with next steps. This will be useful when you want to process resource extensive actions and do not want to wait for an action to complete
