Formulas are used to create Calculated (derived) Indicators from basic indicators in BellaDati.

There are four types of indicators defined by formula:

Formula indicators defined on data set level. These are available in all reports based on this data set.
Formula indicators defined ad hoc on view level in each report. These are available only for the particular view and belong to the two subcathegories:
- Additional formula defined indicators
- Formulas on date/time axis

Creating Formulas

Make sure that you are familiar with Displaying Indicators section prior proceeding with Formulas.

You can edit Formulas only of Calculated Indicators. To create Calculated Indicator:

Calculated indicators can be determined by calculator symbol next to indicator name.

You can leverage autocomplete or lists of availabe functions for rapid formula development.

See Formula Reference Guide for complete specification of available formulas.

Indicators defined by formulas have currently the following limitations in BellaDati:

Sorting by formula indicators is not possible (exception: attribute counts and distinct counts).
You cannot refer to already existing formula indicators from other formula indicators.

Notice that Indicators setting dialog of Calculated Indicator lacks specification of Members and Time aggregation.

This is because you can define it programatically in combination with additional functions.

Member aggregation can be defined by suffixing Indicator with:

Example: use M_SALES@SUM to obtain Total Sales or M_PRICE@MIN to find the lowest price.

Time aggregation can be defined by suffixing Indicator with:

Example: use M_SALES@SUMT to obtain Total Sales in time or M_PRICE@MINT to find the lowest price in time.

Memeber and Time aggreagation can be combined togeter.
