# ConsolidatedAvg TM1 Function: Syntax, Use and Examples

ConsolidatedAvg is used to calculate a single consolidated average value of child values at the n level. For example, if you have three child elements with 10, 15 and 11 in a measure, the consolidated average would be (10+15+11)/3, so 12.

## Syntax of ConsolidatedAvg

In a TM1 Rule, the syntax is:

`['Measure'] = C: ConsolidatedAvg(flag-value, '', Element1, Element2, Elementn, 'Measure');`

And in a Turbo Integrator process, the syntax is similar:

`nAverage = ConsolidatedAvg(flag-value, 'CubeName', Element1, Element2, Elementn, 'Measure');`

Where:

• flag-value is either a 0, 1, 2 or 3.
• 0 use all values
• 1 use the consolidation weighting (so the -1, 0, or 1 in weighting)
• 2 ignore zero values
• 3 combines the above two (in other words, 1 and 2 are not mutually exclusive)
• CubeName is the name of the cube you are working with (not required for the rule version if your rule is addressing the current cube).
• Element1, Element2, Elementn are elements or aliases from dimensions of the cube, in the exact order of the dimensions in the cube (so like they are in a DB). Note that for ConsolidatedAvg you don’t have to use a specific element in each position here. You can use an !DimName in place of a specific element.
• ‘Measure’ is an element from the measures dimension (yes, I know this is superfluous, but your measures dimension should be the last one in the list!)

Note that when using ConsolidatedAvg it take the average of the n level elements, not the immediate children where there are multiple levels in a hierarchy.

## Further Notes from IBM

The following notes are taken directly from IBM. They explain some quicks about the calculation of averages in TM1 that you should be aware of:

• If zero is specified as the weighting of some consolidated elements, then the Tm1s.cfg configuration parameter ZeroWeightOptimization=F must be set for these elements to be included in the calculation of the average value in a consolidation. Without this configuration parameter, the elements for which the weighting is zero are eliminated from the consolidation list, and are therefore not included when calculating the average value in a consolidation.
• If you want cells containing the value zero to be included when calculating the average, UNDEFVALS must be set in the rules for the cube that is specified by the cube-name argument. This ensures that when a zero is assigned to a cell of the cube, an actual zero value is stored in the cell and the zero value is included when calculating the average value in a consolidation.
• If the rules for the cube that is specified by the cube-name argument include a SKIPCHECK statement, zeros are always ignored when calculating the average value in a consolidation. Remove the SKIPCHECK statement from the rule to include zeros in the consolidation average.

## Example of ConsolidatedAvg

Here our example is to calculate the average price from the Price measure in the Subscription cube. We want to ignore zero values.

`['Average Price'] = ConsolidatedAvg(2,'Subscription',!Year,!Month,!Scenario,!Department,!Product,'Price');`

So if in our cube we had the following values:

From these, the average calculation would sum those and divide by 4 (excluding the two zeros), so calculating the average as 15.

## Usage

You can use ConsolidatedAvg in both Rules and TI Processes.
