Using many What If Parameters

Hello All,

Hope everybody doing well.


I have requirement where I have to use 165 user input values. As for my understanding there are two ways of doing it. 


1. Using 165 what if parameters. It seems like the development will be very time consuming. As it's not in the table format. Entering the 165 value will be very hectic for users as well.

2. I will create a database/Excel(Online) stores all the 165 inputs in the table format. That database will be used in power bi. Using power Apps they can update the table.


As the input variables is high, Please suggest some way to be user friendly. If it is easy develop, I will be very happy.

Please feel free to recommend a tool apart from Power BI as well.

What-If parameters allow you to create a dynamic report that updates based on the values of one or more parameters that you can change.

Here are some tips for using multiple What-If parameters in a Power BI report:

  1. Create a separate What-If parameter for each value you want to change dynamically.
  2. Use the What-If parameters in calculated columns, measures, or DAX formulas as needed.
  3. Use the RANKX function or similar functions to perform conditional ranking based on the values of the What-If parameters.
  4. Use the SWITCH function or similar functions to perform conditional calculation based on the values of the What-If parameters.
  5. Use the ALL function or similar functions to remove filters created by the What-If parameters.

It's important to note that What-If parameters are a powerful feature of Power BI, but they can also slow down report performance if used excessively. To avoid performance issues, use What-If parameters judiciously and only when necessary.
