Dinamic dax with filters

Certainly! Here's a clean and friendly version of your reply, tailored for posting in a Microsoft Fabric or Power BI Community Forum:

Hi there! You're running into a common behavior in Power BI when using slicers and matrix visuals on combined tables like yours.

🧩 Why You're Seeing "Tablet" with a Blank "Supported by"

Even though you're filtering Supported by = Tech Store and Year = 2026, the matrix still shows "Tablet" because Power BI keeps all rows from the data unless explicitly filtered out — even if one of the values (like “Supported by”) becomes blank after slicer selection.

✅ How to Fix It

You can solve this by adding a filter that hides rows where "Supported by" becomes blank after slicer filtering.

🔹 Option 1: Use a Visual-Level Filter with a Measure

Create a measure like this:

Show Rows =
IF(
    ISFILTERED('ParameterData'[Value]),
    IF(
        NOT ISBLANK(SELECTEDVALUE('Consolidado'[Supported by])),
        1,
        0
    ),
    1
)

Then apply this Show Rows measure as a visual-level filter to your matrix, and set it to show only when the value = 1.

This will hide rows like "Tablet" where the filtered value doesn’t match and results in blank.

🔹 Option 2: Build a Filtered Table

If you prefer, you can create a filtered version of your union table:

FilteredConsolidado =
FILTER (
    ADDCOLUMNS (
        UNION (
            SELECTCOLUMNS('2024', "Year", 2024, "Product", '2024'[Product], "Supplier", '2024'[Supplier], "Supported by", '2024'[Supported by]),
            SELECTCOLUMNS('2025', "Year", 2025, "Product", '2025'[Product], "Supplier", '2025'[Supplier], "Supported by", '2025'[Supported by]),
            SELECTCOLUMNS('2026', "Year", 2026, "Product", '2026'[Product], "Supplier", '2026'[Supplier], "Supported by", '2026'[Supported by])
        ),
        "YearFilter", SELECTEDVALUE(ParameterData[Value])
    ),
    [Year] = [YearFilter]
        && NOT(ISBLANK([Supported by]))
)

Then use FilteredConsolidado in your matrix visual instead of the original Consolidado.

🔧 Bonus Tip

If you haven’t already, add a Year column when building the union to make filtering easier and avoid relying solely on the slicer context.
