This summary provides overview of all formulas that can be used in reports or data sets (predefined indicators). If you are searching for transformation scripting during data import, see Developer documentation.

## Indicators and codes

Each dataset indicator is specified by its unique code starting with `M_` (M as Measure). Accessing the calculated indicator's value is possible by typing this code directly into the formula. For example:

 ```M_NAME_1 + M_NAME_2 ```

Another way how to get the value of the indicator is to use the `value()` function:

 ```value('M_NAME_1') + value('M_NAME_2') ```
 Strings must be always enclosed by apostrophes: `'L_NAME'`.

Both examples have the same result.

### Drill-down (members) aggregation

Members aggregation determines the way how to count values in the case that exists more records for one selected member in a single time unit. Aggregation type is specified by adding the appropriate suffix to the indicator's code. When not specified, the `SUM` aggregation is applied.

Suffix

Description

Example

`@SUM`

Calculates the sum of all values for the selected drill-down attribute

`M_NAME@SUM`

`@MIN`

Calculates the minimum of all values for the selected drill-down attribute

`M_NAME@MIN`

`@MAX`

Calculates the maximum of all values for the selected drill-down attribute

`M_NAME@MAX`

`@AVG`

Calculates the average of all values for the selected drill-down attribute

`M_NAME@AVG`

`@MEDIAN`
Calculates median of all values for the selected drill-down attribute
`M_NAME@MEDIAN`

`@DC`

Calculates the distinct count of all values for the selected drill-down attribute

`M_NAME@DC`

### Counting of level members

Each drill-down level is represented by particular members, for example the level `City` contains members like `Berlin`, `Paris`, `New York` etc. To get the count of these members, use the following syntax:

 ```L_NAME_COUNT //L_NAME represents the level code (prefix L like level) L_NAME_DCOUNT //to get the unique count use the _DCOUNT suffix instead ```
