Expand a date range

Hi community, 

 

have this one fo you:

 

I have this table called TP (travel periods)

 

Travel StartTravel EndIndex
20/11/201812/12/2018TP1
10/01/20193/04/2019TP2
30/04/201926/06/2019TP3

 

what is needed is another table generated from the expansion of Travel Start and Travel End. Something looking like this:

 

Travel Index
Nov-18TP1
Dec-18TP1
Jan-19TP2
Feb-19TP2
Mar-19TP2
Apr-19TP2

 

this will be the conjuction between other tables to combine data together. 

 

I tried with some variables butt came out to be crap.

 

Thank you for your help

    Alright,

     

    Then righ-click the original table and select Reference --> this creates another table that references the original TP table (i.e. if the TP table gets updated the updates also carry on to the expanded ), then apply the steps needed in the new table to get the desired result and maintain the origianl table.

    Hi Anonymous,

    Here's how to do it with Power Query.

    In the Query Editor, calculate the days in between the end and start dates:

     

     

     

     

     

     

     

     

     

     

     

    Then add another column that generates all the dates between start and end:

    List.Dates([Start],[Subtraction],#duration(1,0,0,0))


     

     

     

     

     

     

     

     

     

     

     

     

    After that, just expand the new column with the date list.

     

    Here's a pbix with everything: pbix

     

    Br,

    T

      Hi Anonymous

       

      thank you for this, however I need the expansion in a brand new table. 

      That's why I would suggest a formulated column/table. 

       

      But the TP table should remain as it is (it has another purpose)
