Are they using same version of Tableau as yours? I noticed this thing while downgrading from Higher Version to Lower, Certain Calculations then behave erratically.
I'm using the latest version of Tableau(2018.3.3) in which value is showing less than the actuals. And In Tableau 2018.3.2, It is showing the correct value.
That's what I thought, Just FIX your CORRECT Values by LODs and Retry. I noticed it in this Forum while downgrading workbooks.
Where should I use LOD if it's showing wrong in my system only not another system?
Dashboard I open in my laptop then Value is less than what it should be but the same dashboard I open in another system then the value is correct.
So you make amendments in yours.
