Hi Experts,

check if this helps you.

Create variable Case1=If([Name]=Previous([Name]) And ([Dept]=Previous([Dept])) And ([Sal]=Previous([Sal]))) Then 1 Else 0

Place this in the Case1 column=Max([Case1]) In ([Name];[Dept];[Sal])

Create variable Case2=If([Name]=Previous([Name]) And ([Dept]=Previous([Dept])) And ([Sal]<>Previous([Sal]))) Then 1 Else 0

Place this in the case2 column=Max([Case2]) In ([Name];[Dept];[Sal])

Hi Amit,

Could you help with non-duplicate case alone. here i would expect case 2 column value to display 1 for both records because it has:

Case 2: same Name Same Dept but different salary

Thanks,

Dinya.

Hi Amit,

Thanks Much this worked great, i have one question in your formula, how to handle if there is any null value in salary measure for both duplicate and non-duplicate cases 1 &2.

Regards,

Dinya.

before doing any calculation add 0 in the measure object like Var1=Sal+0

or other you can try to sort the objects first to get the sequence.
