Global session variable in DAX
Create a DAX variable that only exists for the user session that can be updated though actions such as clicking buttons. These variables would only be in scope for the current user and would differ from a calculated measure in that they could increment (or decrement) based on a action. These global variables could then be used in other calculations (similar to What If) but not the same.
Moved over to power bi recently and I cant believe how these little snags are not yet in the product. Global variables or global session variables to allow dynamic header names and calculations or the ability for dax to use these global variables to evaluate and change text filters etc. to be able to switch between actual vs budget or forecast or any of these combinations without having unnecessary measures cluttering the UI. just two expressions and a selector to update the variable and dax calc.
Is that option existing today? If yes can you please show me how to use it?
