I created a value called 'User'. I also see a value called '$User'. How are they different?
User - A value a builder will have created. $User - Is a system value created by the Boomi Flow engine.
Values with a $ sign before them are system values.
System values are values assigned dynamically by the Boomi Flow engine during runtime, and include information about the flow, the person who starts the flow, users in the flow, geolocation data of the user, etc.
System values are different for each flow, and not explicitly created unless the flow asks for it. (You will therefore not find system values by clicking on Home, and Values.)
