Forward Forecast (Moving Average) based on Cumulative Count Measure

Hi everyone, I've created a measure that calculates the cumulative count of hires and terminations in order to calculate the headcount (hires minus terminations):   HiredStaff = CALCULATE ( ...

    Hi Anonymous 

    Thanks for your reply.

     

    I find the formula it uses involves recursion. However, DAX language doesn't support recursion.

Hi Anonymous 

Thanks for your reply.

It seems that in measure [MovAvg_Headcount], the table in filter function is not same as the table in the other 2.

I will continue to find out the exact reason and the correct [MovAvg_Headcount].

thanks v-xiaotang !

 

I didn't even realize that there is something wrong with the measure [MovAvg_Headcount]. I thought it works, but thanks for letting me know.

 

[MovAvg_Headcount] calculates the moving average for the headcount (meaning the historic data). Would you also have an idea on how to create another measure (or calculated column) to calculate the moving average forecast for headcount (like what I did in Alteryx)? I actually don't really need the moving average for the historic headcount. I just created the [MovAvg_Headcount] measure, hoping that it would help to calculate the moving average forecast.

    Hi Anonymous 

    I have not used this software, so not quite understand the formula Alteryx uses to calculate the moving average forecast for headcount. Can you describe how the result you want is calculated? If you do it manually instead of using Alteryx.

      hi v-xiaotang ,

       

      I've added an excel file (Formula.xlsx) with a formula that calculates the moving average forecast in Excel to the dropbox folder: https://www.dropbox.com/sh/2kw6iplladj84a3/AABJ3N6vfeyw-JxEddf2Hvl-a?dl=0

       

      Here you can see a screenshot of the formula I used in Excel:

      This is the formula:

      =ROUND(IF(H28="";AVERAGE(IF(H27="";J27;H27);IF(H26="";J26;H26);IF(H25="";J25;H25);IF(H24="";J24;H24);IF(H23="";J23;H23);IF(H22="";J22;H22));"");5)

      I would like to recreate a similar formula in Power BI to calculate the moving average forecast in my dashboard. I hope this makes it clearer. If not, please let me know and I'll provide more detailed information.

       

      Best,

      Matisse
