Сделал так:

PHP код:

    FactureJourCreateCust_RU    jourCreate;
    FactureEditLinesEngine_RU   engine;

    OffSessionID_RU             offSessionId;
    OfficialsServ_RU            offServ;

    CustInvoiceJour             custInvoiceJour;


    select firstonly custInvoiceJour
        where custInvoiceJour.SalesId == this.salesTable().SalesId;

    if (OfficialsServ_RU::isFeatureEnabled())
    {
        offServ      = new OfficialsServ_RU();
        offServ.initTableFacture(FactureModule_RU::Cust,
                                 custInvoiceJour.InvoiceAccount,
                                 true,
                                 CustInvoiceJour.creditNote());
        offSessionId = offServ.newId();
    }

    jourCreate     = new FactureJourCreateCust_RU();
    engine         = new FactureEditLinesEngineCust_RU(jourCreate);

    jourCreate.setUnpack(false);
    jourCreate.parmRecalcTaxes(NoYes::No);
    jourCreate.parmShowProgress(NoYes::No);
    jourCreate.parmInBatch(true);
    engine.insertJour(custInvoiceJour);

    jourCreate.initParameters(NoYes::Yes,
                              NoYes::No,
                              PrintOut::After,
                              FacturePrintType_RU::Original,
                              custInvoiceJour.PrintStandardCurrency_RU,
                              '',
                              custInvoiceJour.InvoiceDate,
                              custInvoiceJour.InvoiceAccount,
                              custInvoiceJour.CurrencyCode,
                              FactureType_RU::Invoice,
                              engine.consignee(),
                              engine.consignor(),
                              offSessionId);

    jourCreate.run();

    jourCreate = null;
    engine = null; 


Работает. Спасибо Георгию и Мише Андрееву.
Жаль, что SalesFormLetter не заработал
