Month Over Month Variance in the Row

Right in that case you might want to calculate your variance using an Account member (create new one) and use that member in the second row. I think that should work

Thanks for the suggestion, I could probably put this in a UD8 and make it dynamic for all accounts but for the purposes of this thread, below is what I ended up using as the solution as a dynamic reporting account.

----------

'Variance to Prior Month:

'This account member is for reporting purposes.
'It displays the variance of the Cost of Sales relative to the same time period for the prior month.
Dim selectedTime As Member = api.Pov.Time
Dim viewMember As ViewMember = ViewMember.GetItem(api.Pov.View.MemberPk.MemberId)
If viewMember.IsAnnotationType Then
'Return an empty string if this is a text-based dataCell.
Return ""
Else
'Returns Cost of Sales for the current time period less the Cost of Sales for one month prior. Should only be used for V#MTD
Return api.Data.GetDataCell("T#[" + selectedTime.Name + "]:A#Cost_of_Sales - T#[Year(" + selectedTime.Name + ")PeriodPrior1(" + selectedTime.Name + ")]:A#Cost_of_Sales")

End If

Return Nothing
