COUNT , COUNTA DAX Function
Despite the same name of statistical functions, the difference in the way they are used in DAX and Excel exists because in DAX a column has a type, and its type determines the behavior of aggregation functions. Excel handles a different data type for each cell, whereas DAX handles a single data type for each column. DAX deals with data in tabular form with well-defined types for each column, whereas Excel formulas work on heterogeneous cell values, without well-defined types.
Thanks for reply,
Which you had shared that link having one statement...
The difference between those two functions are, COUNTA can count TRUE/FALSE column but COUNT still raises an error.
in my data also have TRUE/FALSE and null data aswell....
COUNT taking everything, it's not throwing any error.
My question....
COUNT, COUNTA, COUNTX, COUNTAX these all functions showing same result...
Note: that link perfectly working in Excel speread sheet, but not in POWER BI. i'm really confusing.
