How to add a Serial Row Number Column in Power BI Table / Matrix visual?

Hi ShmuelM,

Grabbing in your table just add a measure with the countrows:

Row_Number = 
CALCULATE (
    COUNTROWS(Profit_Table),
    FILTER ( ALLSELECTED ( Profit_Table ), Profit_Table[Position] <= MAX ( Profit_Table[Position]) )
)

As you can see in the print below it counts the number of rows no matter if you have slicer or not, left table is the full data, right table is influenced by slicer.

Please be aware that this measure is influenced by the order of your Position so if you want to order by another column this will give you the row number in a different order also.
