Dates between create columns

Hi guys, i need some help

 

I have a table with Start Date and End Date for each employee

I need to create one row for each day between these two date, repeating the employee names.

 

Is there a way to do that?

I had a similar usecase within my work environment and I solved this using M powerquery.

 

They idea is to create a list with dates between the start data and the enddate

 You can create a new column containing the list with dates as followed:

 

Table.AddColumn(  #"PreviousStepName", "NewColumnName", each List.Dates([Startdate], Duration.Days([Enddate] - [startdate]), #duration(1,0,0,0)
    ))
 
With this code you get a new column containing for each row a list with dates between the startdate and enddate. In the next step you simply expand the list and as a result you get a row for each date between the startdate and enddate.
 
For example when the startdate is 1-1-2023 and the enddate is 10-1-2023 you get a row for each day.

In this case, the last day isnt beeing created, what parameter defines that?

Do you mean if the enddate is null? You could choose to replace those values with the date from DateTime.LocalNow from https://learn.microsoft.com/en-us/powerquery-m/datetime-localnow

 

If that isn't what your saying could you then provide a small example table with dummy data

Add 1 to the "Count" parameter:  

 

List.Dates([Start], Duration.Days([End] - [Start])+1, #duration(1,0,0,0))

You could create a calculated table in DAX

Employee dates =
SELECTCOLUMNS (
    GENERATE ( Employee, CALENDAR ( Employee[Start date], Employee[End date] ) ),
    "Employee first name", Employee[First name],
    "Employee last name", Employee[Last name],
    "Date", [Date]
)
