    how to calculate average time for  when dates are missing or multiple entries on same date in range in qlikview.


      Hi Experts,


                I want to calculate the average time of last successful 7 times reload of qvd. If some qvds are scheduled on daily basis so I can get last 7 days qvd reload time,if some qvds are refresh on weekly basis so I should  get last 7 weekly reload time,and if some qvd's  refresh more than 1 time in a single day then I should get that day entries.I'm successful to get those entries.

      But My average time is not coming correct.I want to predict that In future at this time in a day qvd should reload that is why I want to get average time or approximate time.

      I have build below formula but It failed to calculate the average for 1st example where I have 4 entries on same day.And If dates are missing in between days then also it gave correct time.(for that I have used interval.)


      interval(AVG(Time(Frac(TimeStamp#(End,'MM/DD/YYYY hh:mm:ss TT'))))) AS AverageTime_To_Load



      Below is my code:



      load distinct

      QVD ,


      Time(End) as END_TimeStamp,


      AutoNumber(End, QVD) as Check

      Resident Incremental where AutoNumber(End, QVD)<=7 Order By QVD, End desc;

      drop table Incremental;


      load QVD,

      interval(AVG(Time(Frac(TimeStamp#(End,'MM/DD/YYYY hh:mm:ss TT'))))) AS AverageTime_To_Load

      Resident Last7Time group by QVD;

      drop Table Last7Time;



      Please help me on this as it is very urgent issue.


      Thanks ,
