# 2d12lift0

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

| Parameter | Description |
| --- | --- |
| Dimensions | Discrete field(s). All fields must come from the same table. |
| Name | Name 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. |
| Function | COUNT / SUM / AVG / MIN / MAX / STDEV |
| Post | **2d12lift0** |
| 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. |
| Axis | 0 / 1. Y-Axis to use when plotting graph. Default = 0 |
| Plot | Y / N. Specifies whether measure’s output column should be plotted on graph. Default = Y |
| Resolve | Optional. 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. |
| Popup | Default / 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:= |
