|---|---|
column |
The column in which you want to find the largest value. |
expression |
Any DAX expression which returns a single value. |
Return value
The largest value.
Remarks
When comparing two expressions, blank is treated as 0 when comparing. That is, Max(1, Blank() ) returns 1, and Max( -1, Blank() ) returns 0. If both arguments are blank, MAX returns a blank. If either expression returns a value which is not allowed, MAX returns an error.
TRUE/FALSEvalues are not supported. If you want to evaluate a column ofTRUE/FALSEvalues, use the MAXA function.
