      2d12lift0

      (A - B) divided by B, where B is 12 rows prior to A.

      1. Calculates ratio of Row(X) -Row(X-12) (12)
      2. Divides ratio by Row(X-12) (lift)
      3. Resets when dimension 1 changes.  (2d)
      4. Result of first 12 rows in the sequence are 0. (0)

      Purpose

      Use this function to: 

      • Calculate year on year lift when one of the dimensions is in months

      Calculation

      d12lift0= Ratio[x/(x-12)] / Row[X-12]

      Ratio[x/(x-12)] = Row(X) / Row(X-12)
      Row(X)= value for current row
      Row(X-12) = Value for row 12 rows prior

      Sample Result

      Parameters

      ParameterDescription
      DimensionsDiscrete field(s).    All fields must come from the same table.
      NameName to be displayed as Column Header in result grid
      Measure

      The field to be used in the post-function calculation.

      • Must be numeric if Function is anything other than COUNT.
      • Must come from same table as DIMENSIONS.
      • Supports Discrete or Continuous DataTypes.
      FunctionCOUNT / SUM / AVG / MIN / MAX / STDEV
      Post2d12lift0
      Value

      Optional.   Filter to apply when evaluating FUNCTION.   Only records in the Filter Recordset will be included in the Function and Post-Function calculations.

      Must come from same table as DIMENSION/MEASURE or be linked to the Dimension table.

      Axis0 / 1.    Y-Axis to use when plotting graph.     Default = 0
      PlotY / N.   Specifies whether measure’s output column should be plotted on graph.  Default = Y
      ResolveOptional.   Resolve level for the measure.   If blank, Resolve = Dimension Table
      Series Type

      Default / Bar / Stacked Bar / Line / Spline / RangeLow / RangeHigh / CSLow / CSHigh / CSOpen / CSClose

      Determines the graph style for the measure.

      PopupDefault / None / Extended
      Prefix$ / £ / E / %

      Usage Notes

      Useful for year on year calculations when one of the dimensions is in months.

      Sort order is important - Ascending / Descending Label / Value. 

      Example

      NOTE: Measure 1 is included purely for illustration. It is not necessary to include this measure for the calculation to work.


      Example use: Year on Year calculation of Sales by Product Group 

      Dimension: [transaction].[product_group], [transaction].[yearmonth]

      Measure 1

      • Name: = sum sales
      • Measure:  =[transactions].[castprice]
      • Function: = sum
      • Post: =
      • Value: =
      • Axis: =0
      • Plot:=Y
      • Resolve:=
      • Series Type:=Default
      • Popup:=Default
      • Prefix:=

      Measure 2

      • Name: = 2d12lift0
      • Measure:  =[transactions].[castprice]
      • Function: = sum
      • Post: = 2d12lift0
      • Value: =
      • Axis: =0
      • Plot:=Y
      • Resolve:=
      • Series Type:=Default
      • Popup:=Default
      • Prefix:=
