This is the code fragment I use for successful purchases.

    let price = (package.storeProduct.price as NSDecimalNumber).doubleValue
    let currency = package.storeProduct.priceFormatter?.currencyCode ?? "USD"
    let productId = package.storeProduct.productIdentifier
    
    let purchaseParams: [String: Any] = [
        AnalyticsParameterTransactionID: transaction.transactionIdentifier,
        AnalyticsParameterCurrency: currency,
        AnalyticsParameterValue: price,  // Critical for revenue reporting
        AnalyticsParameterItems: [
            [
                AnalyticsParameterItemID: productId,
                AnalyticsParameterItemName: package.storeProduct.localizedTitle,
                AnalyticsParameterItemCategory: "Subscription",
                AnalyticsParameterPrice: price,
                AnalyticsParameterQuantity: 1
            ]
        ]
    ]
    
    Analytics.logEvent(AnalyticsEventPurchase, parameters: purchaseParams)
    
    Analytics.logEvent("revenue", parameters: [
        "amount": price,
        "currency": currency,
        "product": productId
    ])

In my project, the “Purchase” event successfully falls into my events with purchases, as you can see on the screen, but there is no metric in the “Goals” tab when creating an AB test. I need to use the “Purchase Revenue” metric, how can I access it?
