I'm new to power query and would love some help with this custom fuction counter
i have the below M code.
(totalLoops as number, optional Loop as number, optional Value as number, optional counter as number) =>
let
currentValue =
if Value = 0 then counter = counter +1
else counter=counter,
currentLoop =
if Loop is null then 1
else Loop + 1,
output =
if currentLoop = totalLoops
then counter
else @#"fxLoop - 1"(totalLoops, currentLoop, currentValue)
in
output
below is the desired result.
when a 0 is found start counting at 1 until the next 0
at the next 0 output a 2 and so on....
Solved! Go to Solution.
What's the point constructing a recursive func whereas there's simple native Table.Group() available?
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlCK1YlWsgCTxmDSEExCxC0xRAyRSCMkcRMwaQYmTZFIIyRxCwyTzZViYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Data", Int64.Type}}),
#"Grouped by 0" = Table.Group(#"Changed Type", "Data", {"Grp", each _}, 0, (x,y) => Number.From(y=0)),
#"Added Index" = Table.AddIndexColumn(Table.RemoveColumns(#"Grouped by 0", "Data"), "Index", 1, 1, Int64.Type),
#"Expanded Grp" = Table.ExpandTableColumn(#"Added Index", "Grp", {"Data"}, {"Data"})
in
#"Expanded Grp"
Also, Excel formula is concise enough,
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |
