Hi zlokesh
I think you're incorrect - ISBLANK is checking whther a given expression is BLANK or not, returning TRUE/FALSEhttps://msdn.microsoft.com/en-us/query-bi/dax/isblank-function-dax
BLANK() will return a blank/null value

It's not quite correct though because if they use the blank in a calculation it will count as 0 not NULL. Which will introduce errors.
As in this article https://www.sqlbi.com/articles/how-to-handle-blank-in-dax-measures/
