Combining dates as text in a grouping step
Hello,
I'm trying to group so that I have columns containing text separated by commas, one of which will group dates producing this kind of output in each cell
"12 Mar 2021, 13 Apr 2021"
This is the M for the step that I have tried:
= Table.Group(#"Added Custom1", {"Referral Reference", "vs Target"}, {
{"MDTs", each Text.Combine([Type],", "), type nullable text},
{"MDT Dates", each Text.Combine(Date.ToText([Event Date],"dd MMM yyyy"),", "),type nullable text}
})
This columns works fine, creating a list of text, separated by commas:
{"MDTs", each Text.Combine([Type],", "), type nullable text},
So I tried to adapt it for the dates as below but this for this column I get and "Expression.Error: We cannot convert a value of type List to type Date."
{"MDT Dates", each Text.Combine(Date.ToText([Event Date],"dd MMM yyyy"),", "),type nullable text}
I was assuming I could simoply wrap the date field with Date.ToText, but that didn't seem to work. What is the correct syntax / approach?
- the Text.Combine function takes a LIST as input and concatenates the various elements in a single text string.
- the date.totext function takes a DATE TYPE value as input.
in the following expression, you are asking the Date.ToText function to work on a list represented by the column content [Event Date]
{"MDT Dates", each Text.Combine(Date.ToText([Event Date],"dd MMM yyyy"),", "),type nullable text}prova (non ho testato il codice: potrebbero esserci errori di sintassi) a cambiarla nel seguente modo, per consentire alla funzione di agire individualmente su ogni singolo elemento della lista:
{"MDT Dates", each Text.Combine(List.Transform([Event Date], (dtt)=>Date.ToText(dtt,"dd MMM yyyy")),", "),type nullable text}
