calculate current week data using current week and previous week info in DAX

Hi,

I hope everyone's well.

I am trying to create a measure that uses previous week and current week data. The table looks like the following-

 

week_endprofitlossreference_for_1_maynet_product_margin
29/05/2022308640 339779
22/05/20225761366 340111
15/05/20226581494 340901
08/05/20226001198 341737
01/05/20226121794342335342335

 

I am trying to create a measure net_product_margin which is calculated by using last week's net_product_margin value - current week 'loss' + current week 'gain'. Here's the code that I tried but it doesn't work perfectly. This does calculate the net_product_margin value correctly for 8th May 2022 but since I am using the column reference_for_1_may it doesn't calculate the later week net_product_margin value correctly.

 

 

net_product_margin = var _lastweek = CALCULATE('All Measures'[reference_for_1_may], FILTER(ALL('Dim_Date'),'Dim_Date'[End_of_Week] = SELECTEDVALUE(Dim_Date[End_of_Week]) -7 )) RETURN _lastweek - 'All Measures'[loss] + 'All Measures'[profit]

 

 

This is how the formula looks in excel.

I have the data from 1st May 2022 in my table so to have a reference I have added a reference column called reference_for_1_may that acts as reference data to calculate later week net_product_margin. I am scratching my head on this. Any help would be much appreciated.

Thank you.

New Column

net_product_margin_calculated = 
VAR ReferenceValue = 342335
VAR FirstDateEver = MIN ( 'P&L'[week_end] )
RETURN
    SUMX ( 
        FILTER ( 
            'P&L', 
            'P&L'[week_end] <= EARLIER ( 'P&L'[week_end] ) 
                && 'P&L'[week_end] > FirstDateEver
        ), 
        'P&L'[profit] - 'P&L'[loss]
    ) 
    + ReferenceValue

Hi @tamerj1 

Thank you so much for the response. I am trying to replicate this but getting an error with EARLIER function. error.JPG

 

@Anonymous 

The solution is based on a calculated column not a measure
