# Averages

#1

Please see code below, is there a simple way of saying that if the sales for the day is 0 then use the previous calculated 21 day average. You will see that I have put some dummy code in for the column [C&U 21DA].

Current code:

select *
, Sum(data.[R&D]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [R&D 21DA]
, Sum(data.[M&E]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [M&E 21DA]

, Case When Sum(data.[C&U]) >0 Then Sum(data.[C&U]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 **
** Else 1 End as [C&U 21DA]

, Sum(data.[DPM]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [DPM 21DA]
, Sum(data.[TP.com]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [TP.com 21DA]
, Sum(data.[OSS]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [OSS 21DA]
, Sum(data.[Group]) Over (order by DocumentDate rows between 20 preceding and current row) / 21 as [Group 21DA]
, Cast(Cast(Convert(datetime,DocumentDate) as float) as bigint)+2
