Iterating over rows based on filter to write multiple if else statement and perform calculations

ankita80486_0-1658854521764.png

In the above table:

1. Need to FILTER  by ([Month Name not equal]="Y"  and based on Asset Number) , since there are many other assets and this has to be done for each asset, ([Month Name not equal]="Y" will filter be Feb March April

ankita80486_1-1658854649413.png

 

2. I need to write conditions and then update the next value for New DT

   IF[New DT] >= [Hrs Bw St and End Date] then [Hrs Bw St and End Date] else  [New DT] (1779.55>=520.04)  result of new column 520.04

  Update [New DT for next month(March)= [New DT]- [Hrs Bw St and End Date] New DT (March)-->1259.51

  IF[New DT] >= [Hrs Bw St and End Date] then [Hrs Bw St and End Date] else  [New DT] (1259.51>=744)  result of new column 744

  [New DT for next month(April) = [New DT] - [Hrs Bw St and End Date] (April)--> 515.51

  IF[New DT] >= [Hrs Bw St and End Date] then [Hrs Bw St and End Date] else  [New DT] (515.51<=516.5) result of new colum 515.51

 

MonthNew column for DT
Feb520.04
March744

Can someone help please??

@ASI80486 create this calculated column:

 

Final Column = 
VAR _asset = 'asset_downtime (3)'[Asset Number]
VAR _time = 'asset_downtime (3)'[Start Date]
VAR _total = SUMX(FILTER('asset_downtime (3)', 'asset_downtime (3)'[Asset Number] = _asset && 'asset_downtime (3)'[Month Name not equal] = "Y"),'asset_downtime (3)'[New DT]) 
VAR _substract =
    SUMX(
        FILTER(
            'asset_downtime (3)',
            'asset_downtime (3)'[Asset Number] = _asset 
                && 'asset_downtime (3)'[Month Name not equal] = "Y" 
                    && 'asset_downtime (3)'[Start Date] < _time
        ),
        'asset_downtime (3)'[Hrs Bw St and End Date]
    )
VAR _result = 
    SWITCH(
        TRUE(),
        'asset_downtime (3)'[Month Name not equal] = "N", 'asset_downtime (3)'[New DT],
        'asset_downtime (3)'[Hrs Bw St and End Date] <= 'asset_downtime (3)'[New DT], 'asset_downtime (3)'[Hrs Bw St and End Date],
        _total - _substract > 'asset_downtime (3)'[Hrs Bw St and End Date], 'asset_downtime (3)'[Hrs Bw St and End Date],
        _total - _substract
    )
RETURN
    MAX(_result, 0 )

In Power Query, go to Add Column > Add conditional column. There you'll have a user interface that produces a series of if (else) statements. Start from there, and if you can't do exactly what you want from the UI, you can always tweak the generated code manually from the Advanced Editor.

here the issue is to update the New DT column with new value and then use that updated new DT value in the next IF statement to calculate the next value in the new column

Oh, I see, it's on a row-by-row basis. I don't think there's a solution using purely the Power Query UI, I think you'd have to add an index column and write some M code. It's probably something I'd solve in DAX though. Sorry I don't have time to flesh it out further, maybe other people will chime in.
