Hi @Nolock
I have to take the first and last value of FPR of each year in the table and substract those values
For example for year 2019: 20707.28 (26/12/2019 last date of 2019)-2982.06 (31/03/2019 first date of 2019), and then for the next years that can be infinite ( 2020, 2021 2022, 2023 etc ....)
Solved! Go to Solution.
Hi @OscarSuarez10,
I've developed a short PowerQuery query which extracts the first and last value for every year and then substracts them.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("NcvBCQAxCATAXnyHZTWa5GoJ6b+NE8HvwNwrSiiM+skQlTdSAtZiJUZ4yyyZxGrxkkA2GhOiwLEbVsHBadjy3g8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [TIME = _t, FPR = _t]), ChangedType = Table.TransformColumnTypes(Source,{{"TIME", type date}, {"FPR", Int64.Type}}), SortedTable = Table.Sort(ChangedType, {"TIME"}), MinYear = Date.Year(Table.First(SortedTable)[TIME]), MaxYear = Date.Year(Table.Last(SortedTable)[TIME]), ListOfYears = {MinYear..MaxYear}, TableFromList = Table.FromColumns({ListOfYears}), ChangedTypeToType = Table.TransformColumnTypes(TableFromList,{{"Column1", Int64.Type}}), RenameColumn = Table.RenameColumns(ChangedTypeToType, {{"Column1", "Year"}}), MinOfYear = Table.AddColumn(RenameColumn, "MinOfYear", (curRecord) => List.First( Table.SelectRows( SortedTable, each Date.Year([TIME]) = curRecord[Year] )[FPR] ), type number ), MaxOfYear = Table.AddColumn(MinOfYear, "MaxfYear", (curRecord) => List.Last( Table.SelectRows( SortedTable, each Date.Year([TIME]) = curRecord[Year] )[FPR] ), type number ), Substract = Table.AddColumn(MaxOfYear, "Last of year - first of year", each [MaxfYear] - [MinOfYear], type number) in Substract
Another possible solution would be to use Group By Year and then extract the first and last value of every group.
Hi @OscarSuarez10,
the (curRecord) => functionBody is an anonymous function which I've used instead of each. Check the following slide, it should explain it.

That helped me a lot, but I have to choose the max FPR month value and min month FPR value of each year and then substract them...
Okey, Thank You !!
Sorry, I don´t understand, What is "curRecord"?
Hi @OscarSuarez10,
the (curRecord) => functionBody is an anonymous function which I've used instead of each. Check the following slide, it should explain it.
It seaches for the minimum and maximum TIME value of a year and then takes the corresponding FPR value. It is the behaviour from your example. Is it wrong?
