        //-------------------- custtable --------------------------
    if (custTable.RecId == 0)
    {
        custTable.initValue();
        custTable.AccountNum           = custAccount;
        custTable.CustGroup            = custGroupId;

There's just one difference with vendor and customer creating is about separated creating DirParty record. If account is a person instead of organization, you have to use DirPersonName table instead of DirOrganization table:

    VendTable                    vendTable;

    DirParty                        dirParty;
    DirPartyPostalAddressView       dirPartyPostalAddressView;
    DirPartyContactInfoView         dirPartyContactInfo;
    VendGroup                       vendGroup;
    DirPartyTable                   partyTable;
    DirPartyLocation                dirLocation;
    LogisticsPostalAddress          address;
    LogisticsLocation               logisticsLocation;
    DirOrganization                 organization;

    ;

    select firstOnly forUpdate vendTable
        where vendTable.AccountNum == vendAccount;
        //-------------------- vendTable --------------------------
    if (vendTable.RecId == 0)
    {
        organization.Name                    = vendName;
        organization.NameAlias               = nameAlias;
        organization.LanguageId              = CompanyInfo::languageId();
        organization.insert();

        vendTable.initValue();
        vendTable.party                = organization.recid;
        vendTable.AccountNum           = vendAccount;
        vendTable.vendGroup            = vendGroupId;
        vendTable.VATNum               = vatNum;
        vendTable.Blocked              = VendBlocked;
        vendTable.TaxOfficeName_TR     = taxOfficeName_TR;
        vendTable.insert();
    }
    else
    {
        vendTable.vendGroup            = vendGroupId;
        vendTable.VATNum               = vatNum;
        vendTable.Blocked              = VendBlocked;
        vendTable.update();
        update_recordSet organization setting name = vendName, NameAlias = nameAlias
            where organization.RecId == vendTable.Party;
    }
