How to remove full table aggregation from a calculation for percentage

I have a calculated column that is taking the average of all data in the table but I just want to have the percentage by row.  Basically I am trying to divide DataDay by MonthDays for each mont...

Sample Data

 

I have scrambled the member information for protection and recreated a workbook to use as a sandbox.

 

For some reason I am having trouble recreating some of the formulas in my Dates table and TrendCalcs table.  I am getting an error about circular dependency.

 

I am basically trying to get the latest date of the month the data was refreshed based on service date in order to calculate the trended PMPM.  

 

What I am trying to accomplish is the trended or projected PMPM (per member per month) based on the claim activity received at that point in time in the month.  I am trying to use the max service date for the month which for Jan is 1/31 and Feb is 2/22.  The PMPM is Total Paid/# Members.  To get the Trended PMPM it is total # days in month/max service date for month * PMPM.

 

Yesterday I worked on creating a percent column in the trend calc table that divides (for January) 31/31 for 1.00.  So far we have 22 days of data in February so the calculation for Feb is 28/22= 1.27.  So the Feb PMPM (cumulative) is $466.30 (Total Paid/# Members) but the trended should be 466.30 * 1.27 = 592.20 for the February trended PMPM.

 

I really appreciate any help you can offer.  I have been struggling with this for a week now.  Thank you so much!

    Using the Percent Measure Sean gave me yesterday as well as the Percent column, it is averaging in the measure but it is summing the column.  I removed aggregation from the ones that I could and this is what it shows me.  I am having a hard time filtering down to just that row of data so the PMPMP would be PMPM*1 for January and for February it would be PMPM *1.27.

     

    This is my Percent Column calc

    PercentColumn = CALCULATE(SUM(TrendCalcs[MonthDays])/sum(TrendCalcs[DataDay]),ALLEXCEPT(TrendCalcs,TrendCalcs[FirstDateC]))

      I think I might have it.  I have been scouring msdns Dax library and tried this:

       

      Trended PMPM = CALCULATE('Members Claims'[PMPM]) * [Percent Measure](FILTER(TrendCalcs,[FirstDate]))

       

      and I think it is doing what I want it to do. Fingers crossed!
