Editing the formula
The Tutorial2 report displays the variance between the actual and budgeted gross margin figures in respect of all channels, all points of sale, and all regions. Remember that the CELLGET formula automatically references the default element of any dimension that you do not explicitly reference. So, although the formula in C11 does not explicitly reference the Measure dimension, it returns the value for Gross Margin, which is the default element.
To display the variance in the figures for actual units sold, instead of for gross margin, we can change the formula. The formula currently explicitly references only the Product and Period dimensions. By default, it also references Gross Margin, which is the default element of the Valtype dimension. To display the values for units instead of gross margin, we must add an explicit reference to the Measure dimension:
