Смотрим на упомянутый метод:
X++:
public void initFromInvoiceJour(CustVendInvoiceJour _invoiceJour)
{
this.CurrencyCode = _invoiceJour.CurrencyCode;
this.OrderAccount = _invoiceJour.OrderAccount;
this.SalesPurchId = _invoiceJour.Num;
this.InvoiceDate = _invoiceJour.Correct_RU ? _invoiceJour.CorrectedInvoiceDate_RU : _invoiceJour.InvoiceDate;
this.InvoiceId = _invoiceJour.Correct_RU ? _invoiceJour.CorrectedInvoiceId_RU : _invoiceJour.InvoiceId;
this.RefRecId = _invoiceJour.RecId;
this.EndDiscPct = _invoiceJour.SalesOrderbalance ?
_invoiceJour.EndDisc_RU / _invoiceJour.SalesOrderbalance * 100 :
0.0;
this.OffSessionId = _invoiceJour.OffSessionId_RU;
}Находим "line 6". И внимательно смотрим на нее и вокруг (одновременно
)
