Creating multiple date tables in one table

[ErikBI]

Hey guys,

I have this certain thing I'm trying to create, but I lack the skills for it. It's hard to exlain in the title, so Ill try to be as clear as possible with my data below:

My input data looks like this:

Phase is just a code for a project. Start and end mark the start and end date of said phase.

What I'm trying to achieve is a date table that looks like this, where a row is created for each day between the start and end per phase. So for phase A I'd have 356 rows created for each day of the year, and after that it goes on to phase B where it creates a row for each day between 1-5-2019 and 31-12-2019, etc.

I recently learned how to create a date table, but this phase thing adds an element that is beyond my skill level. I hope some someone knows how to achieve this, because it will help me a lot!

Thanks!

Hi , @ErikBI 

Click New source ->create  a blank query->advanced Editor

Then paste following M code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTLUN9Q3MjC0BDGN9I2hnFidaCUnoJAppqyRAVjWGbteqKwLUMhc38gIJm2qb2SJkHXFK+uGJovmLHe8mj3wynrilfXCK+uNWzYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Phase = _t, start = _t, end = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Phase", type text}, {"start", type date}, {"end", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Duration.TotalDays(Date.StartOfDay([end])-Date.StartOfDay([start]))),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each List.Generate(()=>[Custom], each _ >= 0, each _ - 1)),
    #"Expanded Custom.1" = Table.ExpandListColumn(#"Added Custom1", "Custom.1"),
    #"Added Custom2" = Table.AddColumn(#"Expanded Custom.1", "Date", each if [Custom.1]=[Custom] then [start] else  Date.AddDays(Date.StartOfDay([start]),[Custom]-[Custom.1])),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"start", "end", "Custom", "Custom.1"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"Date", type date}}),
    #"Sorted Rows" = Table.Sort(#"Changed Type1",{{"Phase", Order.Ascending}, {"Date", Order.Ascending}})
in
    #"Sorted Rows"

Brilliant! it took a bit of fiddling with the advanced editor to adjust the source data, but it seems to work perfectly now.

Thanks!
