Convert the DAX Query to Power Query to create Custom Column

Hi Everyone,

Please Help me to Convert the DAX Query to Power Query to create Custom Column. Below is the Query.

The below Dax Query is working well as expected in the Desktop, for few reports the column is needed from power query. So I'm trying to convert it in Power Query but getting error. Pasting the Power query also which i tried.

Dax Query
------------

YTD=
VAR selectMonth = MAX('CostPlans_Monthly'[Reporting_MonthNumber])
RETURN
CALCULATE(
    SUM('CostPlans_Monthly'[Value]),
    FILTER(
        ALL('CostPlans_Monthly'),
        'CostPlans_Monthly'[CostPlanName] = SELECTEDVALUE('CostPlans_Monthly'[CostPlanName]) &&
        'CostPlans_Monthly'[Reporting_MonthNumber] <= selectMonth &&
        ('CostPlans_Monthly'[PlanType] = "Actual" || 'CostPlans_Monthly'[PlanType] = "Plan")
    )
)

Power Query
----------------

let
Source = CostPlans_Monthly2, 
SelectMonth = List.Max(Source[Reporting_MonthNumber]),
FilteredTable = Table.SelectRows(
Source,
each [CostPlanName] = Table.SingleValue(Source[CostPlanName])
and [Reporting_MonthNumber] <= SelectMonth
and ([PlanType] = "Actual" or [PlanType] = "Plan")
),
YTDTotal = List.Sum(FilteredTable[Value])
in
YTDTotal


Please help me to fix this

    Hi JaipalAnu 

    You can create a blank query and put the following code to advanced editor

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUXJMLilNzAEyjAyMjPUN9Q2BTEMDpVgdiHRATmIeTNJI3xTMxCppDNZpjJD0L8lILUKVNYHIOmE11xAhieomiF4j7HpRrHVCt9YI2VpnNK0ofnXGsBbFt+h6EdbGAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [CostPlanName = _t, PlanType = _t, Date = _t, Value = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"CostPlanName", type text}, {"PlanType", type text}, {"Date", type date}, {"Value", Int64.Type}}),
        #"Inserted Year" = Table.AddColumn(#"Changed Type", "Year", each Date.Year([Date]), Int64.Type),
        #"Inserted Month" = Table.AddColumn(#"Inserted Year", "Reporting_MonthNumber", each Date.Month([Date]), Int64.Type),
        #"Added Custom" = Table.AddColumn(#"Inserted Month", "Sum_value", each List.Sum(Table.SelectRows(#"Inserted Month",(x)=>(x[PlanType]="Actual" or x[PlanType]="Plan") and x[CostPlanName]=[CostPlanName] and x[Year]=[Year] and x[Reporting_MonthNumber]<=[Reporting_MonthNumber])[Value])),
        #"Sorted Rows" = Table.Sort(#"Added Custom",{{"CostPlanName", Order.Ascending}, {"Date", Order.Ascending}})
    in
        #"Sorted Rows"

    Best Regards!
