Re: Data table Calculation from Same folder

Hi @msarfaraz,


You could have a try with the measue below.


Measure = CALCULATE(MAX('Table1'[Nights]))-CALCULATE(MIN('Table1'[Nights]))

Here is my test output.



If you still need help, please share some data sample which I could copy and make a test.


In addition, you could have a reference of the attachment. 


Best Regards,
