SystemReserved Entity

Custom Activity


C# class built to be used within UiPath REFramework. It will hold values that are required for a REFramework to work correctly, like TransactionNumber, RetryNumber, etc.

The idea of SystemReserved was introduced in the Enhanced-REFramework, defining a dictionary of parameters which group variables required for the framework to work correctly, like TransactionNumber, RetryNumber, etc.

This project takes the dictionary one step further by creating a custom class (SystemReserved) with the following key features and advantages:
  • It simplifies its usage, as it would not require a string key which could introduce errors and also doesn't require the use of CInt to get integer values.
  • FrameworkFolders class which allows developers to access the most typical folders used in the REF without using the path to those directories, which allows to point the folders to other directories without the need to change every place where the folders are used.
  • A dictionary that allows developers to have custom parameters defined at runtime without the need to use another argument and without messing with the Config dictionary.
  • It has two UiPath activities for those who want to have a visual instantiation of a SystemReserved and/or a FrameworkFolders instead of just using a new sentence in an assign or the variables/arguments panel.
  • It has seven UiPath activities that handle the flow handling that needs to be done in the REF.
For more details, check the attached README file.



Simplify usage of SystemReserved, prevent typing errors, among others.


Tested in Studio 2019.10 but should not present any problem in older versions of Studio.
