recalculateServiceTerms

Если есть доступ в базу, поискать можно запросом:

SELECT (SELECT [Name] FROM [SysSchema] WHERE [Id] = [SysSchemaId])
FROM [SysSchemaContent]
WHERE CAST([Content] AS VARCHAR(MAX)) LIKE '%recalculateServiceTerms%'

И среди трёх результатов будет искомая схема CaseServiceUtility:

/**
 * Recalculates scheduled dates by service item.
 * @protected
 */
recalculateServiceTerms: function() {
	var config = this.getIsFeatureEnabled("ServiceTerms")
			? this.getCaseTermCalculatorServiceConfig()
			: this.getCallTermCalculationServiceConfig();
	if (config) {
		if (this.getIsFeatureEnabled("ServiceTerms")){
			this.callService(config, this.onRecalculateCaseTerms, this);
		} else {
			this.callService(config, this.onRecalculateServiceTerms, this);
		}
	} else if (this.get("ResponseDate")) {
		this.set("ResponseDate", null);
		this.set("SolutionDate", null);
	}
},
