Injecting a Dynamic Variable into an Analysis Services Query for Filtering Analysis Serv. Cube Data

[leina_daniel]

Hello Fabric Community,

I'm currently working with Analysis Services to query an anaylsis services cube and need some help with injecting a dynamic variable into the middle of my query. I have a weekly-updated list of budget codes that I want to use to filter my data, but I haven't been able to figure out how to properly incorporate this variable.

Below is an example of the query I'm working with the following DAX:
EVALUATE
// We want to get Var BC's from a different query
VAR BudgetCodes = {"TXP3GA182632","TXP3HQ01","TXP3HQ01D","TXP3HQ01GC","TXP3HQ01SPC"}
RETURN
SUMMARIZECOLUMNS(
'Dim PO Budget Code'[Budget Code],
'Dim Cost Center'[Cost Center Name],
'Dim Invoice Link'[Invoice Link],
KEEPFILTERS( TREATAS( BudgetCodes, 'Dim PO Budget Code'[Budget Code] )),
KEEPFILTERS( FILTER( ALL( 'Dim Cost Center'[Cost Center Code] ), NOT( ISBLANK( 'Dim Cost Center'[Cost Center Code] )))),
KEEPFILTERS( FILTER( ALL( 'Dim PO Budget Code'[Budget Code] ), 'Dim PO Budget Code'[Budget Code] <> "0" )),
"PO Ordered Amount Excluding Tax USD", [PO Ordered Amount Excluding Tax USD]
)
ORDER BY
'Dim PO Budget Code'[Budget Code] ASC,
'Dim Cost Center'[Cost Center Name] ASC,
'Dim Invoice Link'[Invoice Link] ASC

Hello @leina_daniel ,
Thanks for posting your query in the Microsoft Fabric Community. The approach to dynamically filtering budget codes depends on your connection mode in Power BI

1. Dynamic M Query Parameters work only in DirectQuery mode.

2. Dynamic M Query Parameters are NOT supported Live Connection

Instead, use slicers linked to a budget codes table or configure RLS in SSAS for filtering.

Thanks for your continuous inputs for the community @lbendlin .

To provide the most accurate solution, could you confirm whether your report is using DirectQuery, or a Live Connection?

The report uses a DirectQuery connection. Apologies for not clarifying sooner!

Thanks for sharing the update. Since your report uses DirectQuery, you can make budget code filtering dynamic without hardcoding it in your DAX query. 

1.Use a slicer linked to a budget codes table to filter the data dynamically.

2. If needed, set up Row-Level Security  in SSAS to restrict data based on user selection.

For an advanced option, you can try Dynamic M Query Parameters. This lets you filter directly in Power Query with parameters. Just make sure the Dynamic M Query Parameters feature is enabled under Options → Preview Features, and it's properly linked to your budget codes.

FYI:

I hope this helps...

Dynamic M Query Parameters are only available for Direct Query data sources, not for live connections.

In this case, we are using a DirectQuery. Not a live connection
