ReFramework is a UiPath template that you can build upon to create your automation. The framework offers a way to handle common project tasks. Here are some advantages of using ReFramework: 

• Easily store, read, and modify configuration data
• Handle exceptions and retry failed transactions
• Extensive event logging for all exceptions
• Automate complex processes using defined states

The framework is recommended for creating scalable and robust automation with UiPath. 

Here is an overview of ReFramework and its states:

ReFramework uses the concept of state machines. It has four states to build robust automations. These states are as follows:

1. Init State: In this state, we initialize the automation. This includes the following:
   • Initializing the settings; for example, the loading of configuration data from the config file
   • Initializing the applications; for example, logging in to applications using credentials
   • Killing all working processes; for example, killing open applications
2. Get Transaction Data State: Used to get data from spreadsheets, databases, emails, web APIs, or Orchestrator queues. It has two possible outcomes:
   • New Transaction: If TransactionItem contains data, process it.
   • No Data: If TransactionItem is Nothing, go to End Process.
3. Process Transaction State: This where all the processing work for transactions takes place. It results in three conditions:
   • Success: In the case of a business rule exception, we log it and go to the next transaction.
   • Rule Exception: If we have a business rule exception, we log it and move to the next transaction.
   • Error: If we have an application exception, we close all programs. 
4. End Process State: We will close all the applications and processes here. 
   • Close All Applications: This will soft close all working applications.
   • KillAllProcesses.xaml workflow: This kills all the working processes.
