You can now run your application functionalities in simulation mode to assist an end user when certain operation could not be performed. The simulation mode enables you to replicate the user functionality to troubleshoot any erroneous workflow by effectively capturing the audit trails. The audit trails that are captured are discrete to the simulation mode and help identify a glitch easily. However, the simulation mode restricts CRUD operations to avoid any modifications to the application data.
