Self-populating table

I'm looking to build a table that references a database. Basically, on the last day of each month I want to count the number of rows in the database and record it with the associated month. I'd like to generate a new row with this number each month. I can do this manually right now, but it would be great to do it automatically. Is this possible in Power BI Desktop? The database is connected via DirectQuery but importing it is an option if need be.

    Hi masons21 

    If all tables have a date stamp you can just use it as a group by in your visual and create a measure that does cont rows on each table.

    COUNTROWS( table )

      Thanks for your suggestion Mariusz 

       

      That's not exactly what I need to do - I can use the COUNTROWS function but I need the total number of rows in the database each month, regardless of when the rows were generated. So the dates associated with them are meaningless for this purpose as there may be carry-over each month. I need a new row to be generated in a new table each month that populates with the total number of rows in the database at that time.

        Hi masons21 

        You can not insert rows in query editor ( to my knowledge ), if you are working with direct query ( sql I'm guessing ) you might as well do it there.

        If no one is removing records from your tables ( should not happen anyway ), you could create a measure with running total like below.

         

        Measure = 
COUNTROWS(
    FILTER(
        ALL( 'Table' ),
        'Table'[createdDate] <= MAX('Table'[createdDate] )
    )
)

        This would return 

         



        Based on dataset

    hi, masons21 

    Power bi could only add column data, for your case, I think you could use the logic to create a measure or a calculate column for it.
