Dynamic M query with arbitrary values
- 1 year ago
Hi rnola16,
Thank you for reaching out to the Microsoft Fabric Community Forum.
You're on the right path using dynamic M query parameters in DirectQuery mode. Since you're passing values like birth_dt and ssn, here are a few ideas that might help troubleshoot:- Make sure both parameters are correctly linked to slicers using dummy dimension tables. This is essential for dynamic input from the report UI.
- Double-check that the names of the parameters you're using throughout the query are consistent mismatched names can cause unexpected behaviour.
- Confirm that Power BI can fold the filters back to the source system. If the filtering isn't being pushed down to the database, the dynamic behaviour may not work as expected.
- It's generally recommended to avoid directly embedding parameter values into custom SQL strings for both security and performance reasons. Power BI handles parameters more effectively when they’re passed and processed using native filtering.

This section relates to his blank dummy dimensions
FilterList = if Type.Is( Value.Type(SalesOrderNumber), List.Type)
then SalesOrderNumber else {SalesOrderNumber},
If checks if it is a list, if yes return it. If a single value it casts it as a list. These are the values passed through from the report, when user provides values
Then filters his table from SQL server, where [SalesOrderNumber] exists in the list from above
#"Filtered Rows" = Table.SelectRows( #"Removed Other Columns", each List.Contains( FilterList, [SalesOrderNumber]
)
The parameter name and the column name are defined with same name and its confusing what is the colum and what is the parameter in here.
