A formula has two parts
Every saved formula has:- An expression, which describes what to calculate
- A scope, which describes where the formula applies
Properties can have more than one formula
A property can use different formulas in different parts of a model. You might use:- One default formula across the model
- A different formula for a particular department
- One formula for Actuals and another for Forecast
Properties play different roles
A property used as a metric is calculated or aggregated. A property used as a dimension organizes values into groups. When Revenue is shown by Department, both are properties. Revenue is the metric being measured. Department is the dimension used to organize it, and Sales is one segment within that dimension.References follow the current context
A plain property reference normally follows the current segment. If a formula is calculating Revenue for Sales, a reference toHeadcount uses Sales headcount when that property is available in the same context.
You can also ask for a specific segment, several segments, every value of a dimension, or an absolute value that does not inherit the current segment.
