Недопустимая операция: параметр по умолчанию не поддерживается для задержки оконной функции;

У меня есть скрипт MSSQL Server, который мне нужно переписать в Redshift

Вот оригинальная часть из сценария 

    SELECT  cog.OrganizationId,
        cog.ClientId,
        REPLACE(REPLACE(AM, 'IAM: ', 'IMP: '),'AM: ', '') AS AM,
        u.ProcedureCodeString,
        t.MonthBilled,
        t.Month,
        t.Year,
        u.ClientCharges,
        LAG(u.ClientCharges,1,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) AS PreviosMonthCharges,
        LAG(u.ClientCharges,2,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) AS TwoMonthsAgoCharges,
        LAG(u.ClientCharges,3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) AS ThreeMonthsAgoCharges,
        LAG(u.ClientCharges,4,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) AS FourMonthsAgoCharges,
        LAG(t.MonthBilled,3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) AS ThreeMonthsAgoDate,
        DATEDIFF(d,CASE WHEN LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) END,CONVERT(datetime,t.MonthBilled) ) AS DateDifCheck,
        b.FirstMonth,
        b.FirstFeature,
        CASE WHEN u.ClientCharges > 0
                AND LAG(u.ClientCharges,1,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,2,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,4,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) = 0
                AND LAG(t.MonthBilled,3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) > b.FirstMonth
                AND DATEDIFF(d,CASE WHEN LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) END,CONVERT(datetime,t.MonthBilled) ) < 95
                AND DATEDIFF(d,CASE WHEN LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(datetime,t.MonthBilled),3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.ClientId,t.Year,t.Month) END,CONVERT(datetime,t.MonthBilled) ) > 88
                AND u.ProcedureCodeString <> b.FirstFeature
                THEN 1 ELSE 0 END AS CommissionReportFlag

FROM    dbo.Contacts_ClientOrganization cog WITH(NOLOCK)

А вот как я это переписал 

    SELECT  cog.organizationid,
        cog.clientid,
        REPLACE(REPLACE(AM, 'IAM: ', 'IMP: '),'AM: ', '') AS AM,
        u.ProcedureCodeString,
        t.MonthBilled,
        t.Month,
        t.Year,
        u.ClientCharges,
        LAG(u.ClientCharges,1,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) AS PreviosMonthCharges,
        LAG(u.ClientCharges,2,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) AS TwoMonthsAgoCharges,
        LAG(u.ClientCharges,3,0) OVER (PARTITION BY cog.ClientId, u.ProcedureCodeString ORDER BY cog.сlientid,t.Year,t.Month) AS ThreeMonthsAgoCharges,
        LAG(u.ClientCharges,4,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.сlientid,t.Year,t.Month) AS FourMonthsAgoCharges,
        LAG(t.MonthBilled,3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) AS ThreeMonthsAgoDate,
        DATEDIFF(d,CASE WHEN LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) END,CONVERT(TIMESTAMP,t.MonthBilled) ) AS DateDifCheck,
        b.FirstMonth,
        b.FirstFeature,
        CASE WHEN u.ClientCharges > 0
                AND LAG(u.ClientCharges,1,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,2,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) > 0
                AND LAG(u.ClientCharges,4,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) = 0
                AND LAG(t.MonthBilled,3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) > b.FirstMonth
                AND DATEDIFF(d,CASE WHEN LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) END,CONVERT(TIMESTAMP,t.MonthBilled) ) < 95
                AND DATEDIFF(d,CASE WHEN LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) = 0 THEN NULL ELSE LAG(CONVERT(TIMESTAMP,t.MonthBilled),3,0) OVER (PARTITION BY cog.clientid, u.ProcedureCodeString ORDER BY cog.clientid,t.Year,t.Month) END,CONVERT(TIMESTAMP,t.MonthBilled) ) > 88
                AND u.ProcedureCodeString <> b.FirstFeature
                THEN 1 ELSE 0 END AS CommissionReportFlag

FROM    public.contacts_client_organization cog

Но теперь я получаю эту ошибку

[42601] [500310] Amazon Недопустимая операция: параметр по умолчанию не поддерживается для задержки оконной функции; java.lang.RuntimeException: com.amazon.support.exceptions.ErrorException: Amazon Недопустимая операция: параметр по умолчанию не поддерживается для задержки оконной функции;

Как я могу это исправить?

Я нашел ответ на эту проблему в официальных документах 

  LAG (value_expr [, offset ])
[ IGNORE NULLS | RESPECT NULLS ]
OVER ( [ PARTITION BY window_partition ] ORDER BY window_ordering )

У меня есть значение по умолчанию, но reshift говорит, что мне нужно только смещение, поэтому просто удалив значение по умолчанию, сделайте трюк
