Create new bool column depending on previous rows
I'm trying to create a new column named "Exists at least One time"
The output should be like shown in the table below.
I believe that the logic will be :
1- for each path, check how many occurence of the path in the table (AAAA = 3 times)
2- for each occurence, check the Exists column, if one is false "Exists a least One time" = FALSE else TRUE
How to implement this in power query or Power BI custom column ?
Hi ABAXA ，
Here I suggest you to try this code to create a custom column in Power Query.
if Table.RowCount( let _path = [Path] in Table.SelectRows(#"Changed Type",each [Path] = _path and [Exist] = true)) = 0 then "false" else "true"Result is as below.
