Need Dates in Same Row for Each Project in Power Query

Hi Guys,

This is my data in Power Query.

Project ID    Status    Status1Date    Status2Date    Status3Date    Status4Date

1                  Status1    1/1/2022      

2                  Status1    2/5/2022

3                  Status2                          5/5/2022

4                  Status3                                                 3/23/2022

5                  Status4                                                                         7/11/2022

1                  Status2                          3/3/2022

1                  Status3                                                   5/6/2022

3                  Status4                                                                          8/3/2022

 

 

I need output like the below...

Project ID    Status    Status1Date    Status2Date    Status3Date    Status4Date

1                  Status1    1/1/2022      3/3/2022         5/6/2022

2                  Status1    2/5/2022

3                  Status2                          5/5/2022                                8/3/2022

4                  Status3                                                 3/23/2022

5                  Status4                                                                         7/11/2022

 

 

Here I have used Group By of "Project ID" and have taken min of all statuses dates. I am getting correct result.

But Sometimes I may be back to the previous status like 

 

Project ID    Status    Status1Date    Status2Date    Status3Date    Status4Date

1                  Status1    1/1/2022      

2                  Status1    2/5/2022

3                  Status2                          5/5/2022

4                  Status3                                                 3/23/2022

5                  Status4                                                                         7/11/2022

1                  Status2                          3/3/2022

1                  Status3                                                   5/6/2022

3                  Status4                                                                          8/3/2022

1                  Status2                           8/8/2022

 

In this case I need this column also need to show in the final table like

Project ID    Status    Status1Date    Status2Date    Status3Date    Status4Date

1                  Status1    1/1/2022      3/3/2022         5/6/2022

1                  Status1     1/1/2022     8/8/2022         5/6/2022

2                  Status1    2/5/2022

3                  Status2                          5/5/2022                                8/3/2022

4                  Status3                                                 3/23/2022

5                  Status4                                                                         7/11/2022

 

 

 

How can I get it in Power Query?

Could you please help me?

 

 

Thanks,

Suneel K.

Hi @suneelkethagani ,

 

Paste the following code into a new blank query using Advanced Editor to see the steps I took:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bY5bDoAgDATvwjcJfYByF8L9r+HWVLRqUpKW6U46RuKUz0dcUEIiGLxmHkkuLoXaD1c0/gUeV4xXNLoiooV0rRhvaOqthGUv7IcY54c/hD3PwW8nbMGvH39flrcfpAf/PAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Project ID" = _t, Status = _t, Status1Date = _t, Status2Date = _t, Status3Date = _t, Status4Date = _t]),
    chgTypes = Table.TransformColumnTypes(Source,{{"Project ID", Int64.Type}, {"Status", Int64.Type}, {"Status1Date", type date}, {"Status2Date", type date}, {"Status3Date", type date}, {"Status4Date", type date}}),
    remStatusCol = Table.RemoveColumns(chgTypes,{"Status"}),
    groupProjectID = Table.Group(remStatusCol, {"Project ID"}, {{"data", each _, type table [Project ID=nullable number, Status=nullable number, Status1Date=nullable date, Status2Date=nullable date, Status3Date=nullable date, Status4Date=nullable date]}}),
    fillDownNested = Table.TransformColumns(groupProjectID, {"data", each Table.FillDown(_, {"Status1Date", "Status2Date", "Status3Date", "Status4Date"})}),
    fillUpNested = Table.TransformColumns(fillDownNested, {"data", each Table.FillUp(_, {"Status1Date", "Status2Date", "Status3Date", "Status4Date"})}),
    nestedTableDistinct = Table.TransformColumns(fillUpNested, {"data", each Table.Distinct(_)}),
    expandDataCol = Table.ExpandTableColumn(nestedTableDistinct, "data", {"Status1Date", "Status2Date", "Status3Date", "Status4Date"}, {"Status1Date", "Status2Date", "Status3Date", "Status4Date"})
in
    expandDataCol

 

STEP SUMMARY:

remStatusCol = Remove the status column as no longer required

groupProjectID = Group table on [Project ID] and use an 'All Rows' aggregation to create nested project tables

fillDownNested/fillUpNested = just fill all cells in nested tables with dates

nestedTableDistinct = Remove all duplicate rows from nested tables

expandDataCol = Reinstate nested table columns to the main table

 

I get the following output:
