Conversion into Power BI DAX

Hi  Euro0681 ,

I created some data:

Here are the steps you can follow：

1. Create measure.

IF1 =
IF(
   MAX('Table'[Period]) in {"202111","202112","202201"}&&
    MAX('Table'[Amount1 USD])=0,
    MAX('Table'[Amount2 USD]),
    IF(
    MAX('Table'[Period]) in {"202111","202112","202201"},
    MAX('Table'[Amount1 USD]),0))

IF2 =
IF(
    MAX('Table'[Period]) in {"202111","202112","202201"}&&
    MAX('Table'[Amount1])=0,
    MAX('Table'[Amount2]),
    IF(
    MAX('Table'[Period]) in {"202111","202112","202201"},
    MAX('Table'[Amount1]),0))

Sum_Amount =
SUMX(FILTER(ALL('Table'),'Table'[CC]=MAX('Table'[CC])&&'Table'[Period]=MAX('Table'[Period])),[IF2])

Sum_Amount USD =
SUMX(FILTER(ALL('Table'),'Table'[CC]=MAX('Table'[CC])&&'Table'[Period]=MAX('Table'[Period])),[IF1])

Sum_ALL =
var _count=
COUNTX(FILTER(ALL('Table'),'Table'[CC]=MAX('Table'[CC])&&'Table'[Period]=MAX('Table'[Period])),[Period])
var _sumall=
SUMX(FILTER(ALL('Table'),'Table'[CC]=MAX('Table'[CC])&&'Table'[Period]=MAX('Table'[Period])),[Sum_Amount]+[Sum_Amount USD])
return
DIVIDE(
    _sumall,_count)

2. Result:

let
    Source = Table.SelectRows(TB, each List.Contains({"202111","202112","202201"},[Period])),
    #"Amount USD" = Table.AddColumn(Source, "Amt USD", each if [Amount1 USD] = 0 then [Amount2 USD] else [Amount1 USD]),
    Amount = Table.AddColumn(#"Amount USD", "Amt", each if [Amount1] = 0 then [Amount2] else [Amount1]),
    Aggregated = Table.Group(Amount, "CC", {"Aggr", each [#"Amount USD"=List.Sum([Amt USD]), Amount=List.Sum([Amt])]}),
    #"Expanded Aggr" = Table.ExpandRecordColumn(Aggregated, "Aggr", {"Amount USD", "Amount"})
in
    #"Expanded Aggr"
