Referencing Results in Expressions

The document provides technical instructions for referencing results variables in LEAP, detailing the syntax for scaling and filtering by dimensions such as fuel or cost. It specifies that results variables generally require the use of functions like PrevYearValue to reference past data, except when defining calculated Indicator variables.

• LEAP allows users to reference results variables—internally calculated values such as total emissions or costs—using a specific syntax that includes the branch, variable, scale unit, and optional filters.
• Users can apply up to two filters to a result variable using the format 'dimension=element' to include a specific element or 'dimension<>element' to exclude it. Supported dimensions include fuel, cost, time slice, effect, balance category, module cost category, or tag.
• Because results variables are calculated internally, they typically can only be referenced for previous years using the PrevYearValue or LaggedValue functions, with the exception of calculated Indicator variables which may reference present-year values.
