AL call stack:
"Sales Subscription Line"(Table 8068).GetSalesHeader line 4 - Subscription Billing by Microsoft version 27.1.41698.41776
"Sales Subscription Line"(Table 8068).GetCurrency line 4 - Subscription Billing by Microsoft version 27.1.41698.41776

I believe the error occurs because the page is not located in the registry, and when AutoFormatExpression is executed, it ends up calling TestField("Document No.")

field(15; "Calculation Base Amount"; Decimal)
        {
            Caption = 'Calculation Base Amount';
            MinValue = 0;
            BlankZero = true;
            AutoFormatType = 1;
            AutoFormatExpression = GetCurrency();
            trigger OnValidate()
            begin
                TestIfSalesOrderIsReleased();
                CalculatePrice();
            end;
        }    local procedure GetCurrency(): Code[10]
    var
        SalesHeader: Record "Sales Header";
    begin
        GetSalesHeader(SalesHeader);
        exit(SalesHeader."Currency Code");
    end;    local procedure GetSalesHeader(var OutSalesHeader: Record "Sales Header")
    var
        SalesHeader: Record "Sales Header";
    begin
        TestField("Document No.");
        if ("Document Type" <> SalesHeader."Document Type") or ("Document No." <> SalesHeader."No.") then
            if SalesHeader.Get("Document Type", "Document No.") then
                if SalesHeader."Currency Code" = '' then
                    Currency.InitRoundingPrecision()
                else begin
                    SalesHeader.TestField("Currency Factor");
                    Currency.Get(SalesHeader."Currency Code");
                    Currency.TestField("Unit-Amount Rounding Precision");
                    Currency.TestField("Amount Rounding Precision");
                end
            else
                Clear(SalesHeader);
        OutSalesHeader := SalesHeader;
    end;
