The generate is configured as follow :

• Generator strategy : Iterate Over List Strategy
• List Expression :

The generator pushes into variable : yield_ratio_list

In a 'Map' component, the @yield_ratio_list variable is transformed as a map variable :

/* Map yield ratio threshold data */
yield_ratio_threshold: Map<String, Tuple<matiere: String, min: Float, max: Float, average: Float>> = @yield_ratio_list.toMap(keyFunction: x => x.matiere, valueFunction: x => x);

This new map variable is used the following way :

{
	part:input.part
	, final_material_weight_net: evaluated_net_weight
	, final_material_weight_net_source :input.final_material_weight_net_source
	, final_material_weight_gross: evaluated_net_weight IS NULL
		? evaluated_gross_weight
		: yield_ratio>=yield_ratio_threshold[input.rm_name].min AND yield_ratio<=yield_ratio_threshold[input.rm_name].max
			? evaluated_gross_weight
			: evaluated_net_weight / yield_ratio_threshold[input.rm_name].average
}
