## counting consecutive identical values - calculated column

Dear ones,
I need your support, thank you very much!
I want to list (in the "Consecutive Imbalance" column) consecutive records that have a value equal to 1 (from the "Imbalance" column) It is also critical that the entire enumeration calculation must be RESTARTed by changing the value of the "Attribute 1" column.
In the Photo is the column "Consecutive Imbalance" which is what you want to obtain.

I found some solutions but they consume too much memory

Hi @xjsuarexcx ,

If you need a calculated column, here's my solution.

Create two calculated columns.

``````Flag =
MAXX (
FILTER (
'Query1',
'Query1'[Timestamp] <= EARLIER ( 'Query1'[Timestamp] )
&& 'Query1'[Desbalance] = 0
),
'Query1'[Timestamp]
)
``````
``````Consecutive Imbalance =
IF (
'Query1'[Desbalance] = 1,
RANKX (
FILTER (
'Query1',
'Query1'[Desbalance] = 1
&& 'Query1'[Flag] = EARLIER ( 'Query1'[Flag] )
),
'Query1'[Timestamp],
,
ASC
)
)
``````

Get the correct result.

I attach my sample below for your reference.

Hi @xjsuarexcx,

Try something like this:

``````let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Tc/LDcAgDATRXnzmwBryoRZE/20ERdFObnNZPXvOUJSoscqMdDVXdx279Nbpuly3a7hUPRaKYISjzgxJUMISmAbXo+XvJ7RsnuWnrQc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Items = _t, Desbalance = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Items", Int64.Type}, {"Desbalance", Int64.Type}}),
Process = List.Accumulate(Table.ToRecords(#"Changed Type"), {}, (a, n)=> a & {if n[Desbalance] = 0 then Record.AddField(n, "Consec", 0) else Record.AddField(n, "Consec", List.Last(a)[Consec]+1)}),
Output = Table.FromRecords(Process, Value.Type(Table.AddColumn(#"Changed Type", "Consec", each null, type number)))
in
Output``````

Kind regards,

John
