User Input in DAX Query

Hurshemar — Wed, 12 Jun 2024 16:22:04 GMT

Hello,

I have a project set up that is pulling in data from an accounting system. Right now I am pulling in data for "2023_Scenario_1" which is hard coded in my DAX query. I want to be able to have a user select this scenario and have it push that selection into this query. I tried created a new paramater called"Selected Scenario" and I replaced the "2023_Scenario_1" below with @Selected_Scenario but I got an error that this paramter wasn't declared.

EVALUATE
SUMMARIZECOLUMNS (
'Organization'[Asset Final Desc],
'Organization'[Asset Desc],
'FactFinance'[DimCompanyID],
'FactFinance'[DimScenarioID],
'DateGL'[YYYYMM],
'FactFinance'[DimProductID],
'ProjectType'[Project Type Level 1 Name],
FILTER(FactFinance, FactFinance[DimScenarioID] IN {"2023_Scenario_1"}),
FILTER(Versions, Versions[Versions] IN {"Final"}),
FILTER(DateGL, DateGL[YYYYMM] >= "202310"),
FILTER(DateGL, DateGL[Balance Type] IN {"Monthly Balance"}),
FILTER(GrossNet, GrossNet[Gross-Net] IN {"Net"}),
"Total Expense", [Total Expense],
"Revenue", [Revenue],
"Royalties", [Royalties],
)

I've taught 10s of thousands of people DAX. I've seen it all. Normally when I see this approach (DAX queries) it comes from someone that has a SQL background. Generally speaking, this is not how you should approach power BI. Instead do the following

Prepare your data in a star schema
Load all the data you will need for all reports. You should never have to refresh the report based on different user data needs
add slicers to the page to apply filters
forget about writing queries. Instead use the visuals (start with table and matrix) to visually build the output you need. The visual creates the structure/group bys, etc, and measures are replacements for aggregations.
