Current Flow / Inflow / Outflow

Hello Everyone, 

 

I would need your support for the calculations of the below metrics.

 

For every week (Monday to Sunday - column WeekNb), I need to determine:

- Current Flow: the number of records of the first day of the week - Monday; 

- Inflow: the number of new records that appeared during that week, starting Tuesday. We can have cases when a record was present the other day for the first time, dissapears today and appears again tomorrow. In this case, the Inflow for that record is 2. 

- Outflow: the number of records that dissapeared during that week. For this, we need to compare every record, day by day, next Monday included, to see if they are still present. We can have cases when a record dissapeared the other day, appears today and dissapears tomorrow. In this case, the Outflow for that record should be 2. 

 

Many thanks for your support!

    Hi

    I had trouble reconciling your requests with the sample data provided. Please check these discrepancies:

     

     

    If you agree that these 2 "Inflows" aren't correct, given the current data, then the attached file should contain what you need.

      Hi ImkeF , 

      I am sorry, but I do not have the option to attach the excel file. 

       

      For the Week no. 7, results for the below sample are:

      CurrentFlow = 2
      Inflow = 5
      Outflow = 3
