Hi,
I am trying to achieve a task which involves randomly assigining value "2" to one of the rows only. Is it possible to achieve in PBI/Power Query (DAX- not preferred). I have a column called "E Address". For each of the "E Address" I want PBI to assign a 2 to only one of the rows randomly and rest of the rows would be 1.
E AddressRandom Sample
abc@example.com | 1 |
efg@example.com | 1 |
hij@example.com | 1 |
jkl@example.com | 2 |
Thank you in advance
Solved! Go to Solution.
@Zubair_MuhammadThanks for you solution. I picked up cues from your post and another post - http://community.powerbi.com/t5/Desktop/Custom-Column-Randbetween/m-p/216944#M96082
The result is I managed to solve it the way I wanted it. Here is the code.
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], #"Changed Type" = Table.TransformColumnTypes(Source,{{"Email", type text}}), #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1), #"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each 1), #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each Number.RandomBetween(1+[Index]-[Index],100000)), #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom1",{{"Custom.1", Int64.Type}}), #"Inserted Division" = Table.AddColumn(#"Changed Type1", "Division", each [Custom.1] / 100, type number), #"Grouped Rows" = Table.Group(#"Inserted Division", {"Custom"}, {{"Max", each List.Max([Division]), type number}, {"AD", each _, type table}}), #"Expanded AD" = Table.ExpandTableColumn(#"Grouped Rows", "AD", {"Email", "Index", "Division"}, {"AD.Email", "AD.Index", "AD.Division"}), #"Added Custom2" = Table.AddColumn(#"Expanded AD", "Custom.1", each if [AD.Division]=[Max] then 2 else 1) in #"Added Custom2"

Hi @smpa01
First add a column as follows
RandomNumber = RANDBETWEEN(1,100000)/100
Now add another column to get your desired assigned values
Assigned Value = IF ( TableName[RandomNumber] = MAX ( TableName[RandomNumber] ), 2, 1 )
Hi Zubair,
Thanks for your post. Is there way to achieve the result by not using DAX at all?
Hi @smpa01
I think there should be a way using QUERY EDITOR as well....
But I am not aware of it
