Count rows in table visual with Field Parameters

Hello everyone,  I have a question. Before that, I can use the COUNTROWS and SUMMARIZECOLUMNS to caculate the number of rows visible in the visual table. But now we apply Field parameters, how can...

    It's a two step process. Check the article at sqlbi.com . Fields parameters in Power BI - SQLBI

     

    Unfortunately it is not (yet) possible to provide lists of columns instead of individual columns

lbendlin would you kindly create a measure for me, since I am still pretty much confused on how to do that! ğŸ™„

Rowcount = 
SWITCH(concatenatex(parameter,[Parameter],","),
"ACCOUNTING_PERIOD",COUNTROWS(SUMMARIZE(ALLSELECTED('ledger_fy22_qtr1'),[ACCOUNTING_PERIOD])),
"FISCAL_YEAR",COUNTROWS(SUMMARIZE(ALLSELECTED('ledger_fy22_qtr1'),[FISCAL_YEAR])),
COUNTROWS(SUMMARIZE(ALLSELECTED('ledger_fy22_qtr1'),[FISCAL_YEAR],[ACCOUNTING_PERIOD]))
)

    Hi lbendlin ,
    if we have 2 field parameters on our table visual how would that measure look?
    And if the Field Parameter has columns from different tables?

    Imagine a table visual with field parameter like below:

    Measures = {
        ("Total Sales", NAMEOF('Measures Table'[Total Sales]), 0),
        ("Avg Sales", NAMEOF('Measures Table'[Average Sales]), 1),
    }

    and

    Categories = {
        ("Product", NAMEOF('Product Table'[Product]), 0),
        ("Country", NAMEOF('Country Table'[Country]), 1),
        ("Store", NAMEOF('Stores Table'[Store]), 2)
    }


    Thanks.

    Same methodology. Instead of permutations for two columns your SWITCH statement needs to handle permutations over three columns.

     

    The measures field parameters are irrelevant as they don't contribute cardinality.

    True, measures are irrelevant.
    The thing is the different tables, not the number of columns.
    So for example if I have columns from 4 different tables what would I write here?

    COUNTROWS(SUMMARIZE(ALLSELECTED('ledger_fy22_qtr1'),[FISCAL_YEAR],[ACCOUNTING_PERIOD]))

    lbendlinthe problem is when columns from 2 or more different tables are selected in the Field Parameter.

    use the same query as the visual uses when you combine these columns from different tables. SUMMARIZECOLUMNS etc.

    This is as close as I've seen anyone get to the solution I'm looking for. In my situation, the user wants to dynamically add multiple fields from one table, but their are over 100 fields in this table and they could add any combination of fields. I'm trying to think of a way to modify your dax above to account for the endless possible variations of column selections. 

    I'm stumped right now, if you had any thoughts I would love to hear them! Thanks.

    It's all manual, and unmanageable for more than 5 parameters.  You are looking at 2 to the power of parameter count permutations.
