POWER QUERY conditions according to the repetition of specific value

[sushi22]

Hi,

how can I put a condition if a specific value repeats itself continuously (WITHOUT INTERRUPTION) at least 3 times?

I want to see if a cell is ABOVE or equal to 3 at least 3 continuous times:

example:

the yes = the moment when we reach that 3rd time

thank you in advance!

If you post the data (not a picture) i'll have a go.

It might not be today but I'll look at it

I didn't use your data because I didn't trust the site it took me to but I dummied up some test data and I created 2 custom columns in Power Query:

1st column creates a list of last 3 values. Call the column CustomDF

let i = [Index] in { #"Added Index"[val]{i}, #"Added Index"[val]{i - 1}, #"Added Index"[val]{i - 2}}

2nd column tests the previous column for all values above 2.

List.MatchesAll([CustomDF], each _ > 2)

So if you substitute column names and step names in the above this should work for you.

Please let me know.

I noticed that the formula doesn't take into account the product number

example:

how can I create unicity between the products?

when a new products appear in the list, the calculation sould start the counting again if you see what I mean?

It works!! expect for the very last cell

Thanks a lot for your help I really appreciate.!!

In Power Query, there isn't a notion of above or below a row.  You will have to add an index column to use for order or maybe a solution involving Table.Group with GroupKind.Local.

It might make it simpler if you add a helper column "above 2"

Thank you HotChilli.

I am not familiar with GroupKindLocal, can you please help me ? I have done the index part in the file:

let
Source = Excel.CurrentWorkbook(){[Name="Tableau1"]}[Content],
#"Type modifié" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"val", Int64.Type}}),
#"Index ajouté" = Table.AddIndexColumn(#"Type modifié", "Index", 1, 1, Int64.Type)
in
#"Index ajouté"

appreciate your help
